I have a dedicated server centos 6.4 with plesk 12. I created to my existing domain.com an subdomain media.mydomain.com to move store there the images.
I created the subdomain also on provider side (3days ago). I also create an A Record on cloud flare point to my static servers ip (2 days ago). When I enter yet, media.mydomain.com to the browser, I get just a blank page, nothing more. When I check the DNS for my subdomain then i get the following message:
Delegation not found at parent.
No delegation could be found at the parent, making your zone unreachable from the Internet.
Not enough name server information was found to test the zone media.mydomain.com, but an IP address lookup succeeded in spite of that.
I don't know, how i can get my subdomain working, can someone give me tip, how i can accomplish that?
A blank page in your browser actually sounds like a server issue not delivering content. Difficult to look at without knowing the actual subdomain in question.

I'm in the use case where I had nothing on this domain, nothing was started on either side, I just bought the domain on the wrong service.
I imagine it's possible to transfer ownership to AWS, so that I may start managing the DNS from there rather than from dreamhost.
I probably could have purchased the domain from route 53 in the first place but this is now done and I don't want for the year under dreamhost to time out to start using it. nor do I want to use dreamhost to manage this url since dreamhost charges quite a lot more.
I've found the amazon guide that's my exact situation, but as per ususal with these guides they're super afraid of providing a concrete example and get into super abstracts with reused terminology for different meaning resulting in an unusable jumble of uncertainties : https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/migrate-dns-domain-inactive.html
So I've gotten to :
Step 3: Create records (inactive domains)
I've just manually edited the values that were created by default by route 53 when I created that hosted zone to the ones I found in the dreamhost DNS configuration :
but I doubt that's what I have to do to transfer the domain especially since the step after that basically sais to change it back to what it was.
So what is it exactly I'm supposed to do in order to transfer the domain to amazon (route 53)?
Domain registration and DNS resolution are related, but separate entities. It seems like you decided you want route53 to serve your DNS entries. Given that, you have two choices.
Choice 1: Keep domain registered with dreamhost
If you do this, you need to instruct dreamhost to look up DNS entries for your domain at route53. This can be accomplished by setting the NS servers on dreamhost to point to route53. There are detailed instructions for this at AWS here. What you have in your step3 is backwards. Step 3 is just saying if you want HOST.yourdomain.com, to add a entry 'HOST' into the hosted zone. You should not touch the NS or SOA entries on the route53 hosted zone away from their original settings. You can simply delete the zone and start over again.
Background: Dreamhost will populate the NS entries by default and they will be the ones queried how to resolve HOST.yourdomain.com. However, if you don't provide dreamhost any information that they should refer the requests to route53, it has no way of knowing that. You need to tell dreamhost that the NS entries (Nameserver) should point to route53's servers. That way, the user trying to resolve HOST.yourdomain.com will be pointed to route53. When it asks route53 what the IP is, all will be well if you setup your hosted zone to resolve that entry. This is what you are going to do on step 4 from the AWS documentation.
Choice 2: Transfer your domain registration to route53
This is a little more up front work, but may be easier in the long run. You are permitted to transfer the domain to another domain registrar. You'll have to follow instructions at both the giving side (dreamhost) and the gaining side (route53).
NOTE: ICANN does enforce a 60 day lock on moves. If you just registered your domain, you will need to wait 60 days before the transfer process can begin. Also, do not worry about 'double paying' for the year. You are required to purchase at least one more year of domain registration, but it will be appended to the end date of your expiration (it won't start it over). Once you move to route53, especially if you already are using route53 for the hosted zone, you will have one less place to pay and administer.
Additional NOTE: Because of the 60 day lock, if it has been less than 60 days since you created the domain, choice #1 is the only choice during that period if you want to serve DNS records from route53.
I have a domain name at web.com, hosting with another site, and want to setup emails through Google Suite. My memory from previous experience tells me that I should be able to set mxrecords directly inside the domain, but web.com is telling me:
Your domain name is not pointing towards Web.com's name servers, this
means if you want to make any changes, you will need to access the
zonefile at the place where you are pointing them, as control is
there.
The hosting is taking place on another site. So I read the above and think this means I need to contact the guy who handles my hosting to add the records. So I do, and I get this response:
You have to do it through web.com to change dns and add new records.
It is done through domain not hosting
Is someone wrong? Or am I misunderstanding how this process works?
We keep static files (images, javascript, and css) for our websites stored in a Google Storage bucket with different folders for different types of resources. Each file is accessed via its name coupled with a custom subdomain mapped via a CNAME record to the appropriate Google Storage bucket.
This approached has worked fine. Today, however, when attempting to access our main website in Chrome's incognito (private browsing) mode, all pages on the site wouldn't load. After some detective work, we've determined that the problem is with the files stored at Google Storage, which are not loading.
Unfortunately, this doesn't seem to be a problem specific to Google Chrome. It occurs in the private browsing modes in Firefox and Internet Explorer as well (at least on the Windows 8.1 Professional platform we're using for testing).
The problem appears to occur only if we use the CNAME-based approach for accessing a file. For example, if this method is used in a private browser window to access one of our image files on Google Storage,
Image of a crowd on Google Storage - direct access to Google Storage
the file can be viewed without a problem. If, on the other hand, the file is viewed in a private browsing window using the CNAME approach, like this
Image of a crowd on Google Storage - access via CNAME
the image will not load.
What's worse, for reasons we don't completely understand, once this problem occurs in a private browsing window, it will continue to interfere with the proper viewing of the website in regular (non-private browsing) browser windows in the case of some browsers.
Has anyone encountered this problem and, if so, found a solution for it?
Thanks in advance for any tips or suggestions.
UPDATE (2015-05-26)
This problem is still under investigation. It may be ISP-specific, although our ISP (Verizon) believes it is a problem on Google's end. An attempt to resolve the problem yesterday by tweaking some DNS settings seemed to solve the problem, but that was only temporary. We began to experience the problem again today. I will update this posting further as more information becomes available.
ADDITIONAL UPDATE (2016-08-25)
(Note: I originally wrote this update on 2015-05-26, but failed to post it, and discovered it today. I'm adding it to complete the description of the issue.)
This issue has been resolved. I cannot say for certain what the source of the problem was, but I can give further information on what exactly the nature of the problem was and what may have solved it.
As I mentioned in the comments below, this appears to have been an issue that was relatively isolated. Further investigation revealed that the problem was occurring only with access to the particular subdomain through Verizon Internet service (land-based or mobile) in the U.S. I do not know if the problem was a regional problem within the Verizon system, or throughout the entire Verizon system. But I do know it affected both landline and mobile access using Verizon.
The problem also evolved. What started as a problem accessing files at the subdomain in a browser's incognito mode became a problem regardless of what browsing mode was used. That said, it was only a problem if the attempt to load files from the subdomain was used with a browser. The files could be retrieved with no problem with, for example, wget. Also, pinging the subdomain also worked fine over the Verizon network.
As the problem became more acute, I decided to do a thorough check of the DNS settings related to the subdomain. Here is where I discovered what may have been causing the problem. There was a slight discrepancy between the DNS settings at the domain registrar and the (separate) DNS service that we use.
The discrepancy didn't lead to conflicting reports as to how the subdomain should be resolved (which is probably why this problem hadn't occurred in the past). But, if I recall correctly, it led to the DNS service providing the CNAME record for the subdomain, without the registrar's DNS information fully confirming that the DNS service had the right to provide that information.
This discrepancy was corrected. Within an hour or two, the problem resolved itself -- anyone viewing the file using the two links above should be successful with both links.
I cannot say for certain, however, whether the change to the DNS settings we made to resolve the discrepancy, or some updating at Verizon, was responsible for the problem being resolved. I will say, however, that I never reported the issue to Verizon. (I didn't get that far.)
Although the DNS discrepancy had existed for more than a year or two, and had not created any problems that we were aware of, I personally think it is what caused the problem.
On github I have made the CNAME record of my domain name. My domain is registered with crazy domains. I went to crazy domains and entered the ip address for the name server, "204.232.175.78". But it keeps asking for a "hostname". It will not allow me to leave the hostname area blank. In the past I have been told to use a hostname like "ns1.host.com" but I can't seem to find anything like this for github pages.
I tried "pages.github.com" but it refuses that, saying it is not a valid hostname.
What should I use as the hostname?
I believe the issue is that you're updating your nameserver registration, when in fact you should be editing your DNS Zone File. Those are two separate records. The nameserver registration determines who's copy of the DNS Zone File acts as master on the domain. The DNS Zone File is what actually controls A, CNAME, MX, and SRV records (and many more). You should try looking through your domain management system (I'm not familiar with Crazy Domains) to see if you can find a section called "All Host Records" or "DNS Zone Editor".
F#$k crazy domains. They changed their interface to try to get everyone to upgrade to premium. On the hamburger on the right side of DNS settings you can add a record there (not forward) and then the CNAME stuff appears.
Seriously considering changing because of this.
StackMob allows you to setup a custom domain. All you have to do is add a CNAME record for a wildcard '*' pointing to stackmobapp.com
I set it up on my domain registrar 24 hours ago, but it still doesn't resolve. It is going to my web hosting providers server instead of stackmob's server when I type dev.mydomain.com
I kept my nameservers the same (ns1.myisp.com and ns2.myisp.com).
Do I have to change these to something else?
update: its been over a week and my dev.domain.com dont' go to stackmob.
You don't have to change your nameservers. Likely the dns changes hadn't propagated to your nameservers yet. It's been known to take up to 72 hours.
I figured out I have to use my registrars name servers, not my own in order to add A/CNAME records to it.
There is one problem with stackmob though, http://example.com doesn't forward to stackmob, only www.example.com and dev.example.com
