Fetching your public ip with OpenDNS

[menixator]

OpenDNS has a dynamic dns record that resolves to the public ip that sent the DNS request.

dig +short myip.opendns.com @resolver1.opendns.com

The only catch is, you have to use their resolvers. So, with that knowledge, you can add it as an upstream DNS server ( Adguard Home WebUI > Settings > DNS Settings > Upstream DNS Servers ) but only if it matches the myip.opendns.com domain.

[/myip.opendns.com/] resolver1.opendns.com resolver2.opendns.com resolver3.opendns.com resolver4.opendns.com

Now you can do:

dig +short myip.opendns.com

without having to specify the OpenDNS resolvers.

It's still a little long to type so what I have done is, I have ip added as a CNAME record to myip.opendns.com through DNS Rewrites (Filters > DNS Rewrites )

Now, all I have to do is:

dig +short ip

and I can get my public ip.
