I know that a lot of VPN users have it as a homepage to their browser, that is why I wanted to publish this warning.

You can replace it with:

    #!/usr/bin/sh  
dig -4 +short @resolver2.opendns.com myip.opendns.com  

    #!/usr/bin/pwsh  
Resolve-DnsName -Server resolver2.opendns.com -Name myip.opendns.com -Type A | % { echo $_.IPAddress }

    There should be an IPv6 resolver, but I don’t remember and am currently unable to test. My PowerShell skills are also effectively non-existent.

        I saw it used in another comment, and am already aware of the use of curl for such a task, but choose to query DNS services instead—especially in scripts.

          but choose to query DNS services instead—especially in scripts.

          Why? What advantages do you get?

            In order to connect to a site like wtfismyip.com you have to do a dns query for the IP address of the server, then query the http port on that IP address, but what if instead, that first dns query gave the answer to your question?

            I worry less about the service breaking, changing, or otherwise disappearing, over a random website.

            EDIT: Also what was said in a sibling comment.

      Neat, how can you check IPv6? I was able to get my IPv4 address by querying with an A record, but tried with AAAA which doesn’t respond with an answer.

        dig -6 +short @resolver2.opendns.com myip.opendns.com AAAA

        Note: You have to ensure you are actually contacting the server with IPv6.

          Ahh yeah, works with @resolver2.opendns.com so I guess my DNS resolver isn’t supporting IPv6 or something like that?

            This is a service provided by some DNS hosts, with their own special subdomains, and is not universal. They may also require slightly different options.

            Other options include:

            • Google (query for txt record): @ns1.google.com o-o.myaddr.l.google.com

            • Akaimai (query for txt record): @ns1-1.akamaitech.net whoami.akamai.net

            • Cloudflare: @1.1.1.1 whoami.cloudflare

            • Cisco (there are four, as far as can tell): @resolver[1-4].opendns.com myip.opendns.com

            …and likely others.
