IP Address Input from Jenkins to Variable powershell - powershell

Question

I Have Jenkins job that asks for IP Address
$ip = $env:Lan_ip
what the user enter goes to $ip
now $ip is 192.168.10.10 for Example
now I'm trying to insert this variable to FortiGate SSH
Invoke-SshCommand $Firewall -command ‘config system interface
edit port1
set ip $ip 255.255.255.0
end’
but he can not read the $ip I need to make it like INT separate with .
im getting this Error
node_check_object fail! for ip $ip
how can i convert the sting im getting from the user when he enter the ip address in for example --> 192.168.10.10
to usable variable in the code

Answer 1

From what I gather from here is that you need to give the subnet mask as a CIDR-formatted subnet mask like 255.255.255.0/24
To get that CIDR value off a subnet IP address, you can use this function:
function Get-SubnetMaskLength ([string]$SubnetMask) {
# $cidr = Get-SubnetMaskLength "255.255.240.0" --> 20
$result = 0
[IPAddress]$ip = $SubnetMask
foreach ($octet in $ip.GetAddressBytes()) {
while ($octet) {
$octet = ($octet -shl 1) -band [byte]::MaxValue
$result++
}
}
$result
}
So
$subNet = '255.255.255.0'
$cidr = Get-SubnetMaskLength $subNet # --> 24
$subNetAndCidr = '{0}/{1}' -f $subNet, $cidr # --> 255.255.255.0/24
P.S. Always use straight quotes instead of the curly thingies ‘ and ’ in code!
