Does anyone have similar issues?
I've setup my domain on Google cloud,
same configuration as I've setup for another domain which works.
but recently, when I setup another domain, it failed.
I've used dig and nslookup, and it shows "REFUSED".
the headache part is, I've no where to go for support.
nslookup -debug wheelspine.com ns-cloud-c1.googledomains.com
Server: ns-cloud-c1.googledomains.com

I came across this problem with my domains too. After few hours I found out, that some of my domains are hosted on ns-cloud-dX.googledomains.com and some on ns-cloud-cX.googledomains.com. When you use incorrect address, dig shows refused.

I transferred a domain from Godaddy some time ago. I have created an EC2 instance with Elastic IP which works fine but it's not resolving the domain name.
The test in the AWS portal resolves the A record to the correct Elastic IP, but the name just gives:
...... server IP address could not be found.
Try running Windows Network Diagnostics.
DNS_PROBE_FINISHED_NXDOMAIN
People have said that the DNS might still be with Godaddy, but I can't see the domain in my Godaddy account.

A Registered Domain is associated with a number of Name Servers.
Hosted Zones have an NS record that defines the Name Servers to use with the Hosted Zone.
The Name Servers in both these sections need to match for the resolution process to work correctly.

I want to use XMPP server in my app to handle messages but I'm having issues configuring my server. When I login to my Openfire admin panel I get a warning telling me that my DNS configuration appears to be missing or incorrect. My question now is, how can I create DNS SRV records for my host? I have searched all over the net for a solution but none helped me.
My openfire admin page.
the value for the xmpp.fqdn property should be the full network name of the server that is running Openfire, the name that clients would use to connect to Openfire.Maybe your current value is incorrect and you have to edit it.
you can edit fqdn under system properties
That error in Admin Console means that DNS managing records for dialup.org domain doesn't have a SRV record pointing to XMPP service. It seems that you have installed Openfire on a regular desktop and expect it to work on the Internet. For this you have to have some internet domain and have proper DNS records on that domain.
I'm trying to setup postfix in a VPC on AWS where an external server communicates with a postfix mail server in the same subnet.
I'm getting an error from postfix every time I try to connect to postfix from an external client. The error says:
warning: hostname example.com does not resolve to address 54.x.xxx.xxx
connect from unknown[54.x.xxx.xxx]
lost connection after CONNECT from unknown[54.x.xxx.xxx]
I'm suspecting this is related to the IP address that is being pointed to the hostname. When I run:
dig example.com
The 'answer' section outputs this:
;; ANSWER SECTION:
example.com. 60 IN A 10.0.1.132
I've looked at this link: http://www.postfix.org/LINUX_README.html
and I've tried editing /etc/host.conf and the /etc/postfix/main.cf file from that link and a bunch of other things from googling but nothing is working and I still get the same error mentioned above.
Is there a way to configure the VPC or the EC2 instance to point to my public IP address, or can I fix this problem trying to add some more configuration settings for postfix?
I have confirmed with that it's not possible to get DNS Name and environment details (staging vs production) without certificate & management API.
However let's consider my case in that my startuptask(exe) consume REST service to post some data so in that REST service can i do some trick to get DNS name?
I have tried with following
HttpContext.Current.Request.UserHostName however it is same as
HttpContext.Current.Request.UserHostAddress
Please give me suggestion if anyone have you did this type of trick.
Update
Using HostName & HostAddress i am able to get IP of that webrole (confirmed with browser request) but when i try that with nslookup command then it says me that Non-existent domain
Does Azure not support reverse lookup?
Thanks in Advance.
After I study the above details I would say that using above trick, you are getting the external facing VIP address about your service.
Lets consider in that case it would be something as below and if you have port 80 configured with your application you could use this IP address in any browser to verify and you did:
65.52.14.112
Now let's run nslook on IP address and it sure returns what you said:
C:\myTools>nslookup 65.52.14.112
Server: router.belkin
Address: 192.168.2.1
*** router.belkin can't find 65.52.14.112: Non-existent domain
Now for a second lets consider you know the hosted service name (it is my service and I know the name) so lets try to use nslookup with that:
C:\myTools>nslookup azurevmassistant.cloudapp.net
Server: router.belkin
Address: 192.168.2.1
Non-authoritative answer:
Name: azurevmassistant.cloudapp.net
Address: 65.52.14.112
As you can see above the hostname resolves the IP address and that's it. Also you would need to understand in both of the above case you were hitting the Windows Azure loadbalancer not the service itself.
I am able to verify that as of now the Windows Azure does not support "reverse lookup" and if you think that is important it is great chance to let your voice heard and submit the request here: http://www.mygreatwindowsazureidea.com/pages/34192-windows-azure-feature-voting

I create a Bonjour browser to find local server,I can collect many host name,and parser the IP.
But when the network is not stable , I can't find any server in local network...
But if you use ping to find server , it never failed to get server IP
Is there a way to ping external server without using Bonjour or give a host name ???
If I can't get the host name now , how to get all the server IP in local network ???
Thanks for all reply or answers.
