This is the one true answer.
Just an IP, nothing else. And easily curlable.
It's a good old service, but unfortunately it's so old that it doesn't support IPv6 connections
Is it malicious code hosted on the website? Or are they saying that visiting that site is an indicator of compromise because they've malware commonly visiting that site?
Looks like the domain registration expired, according to https://lookup.icann.org/en/lookup
Fortinet marked the website as "malicious", but it doesn't seem to give an explanation as to why it's been given that classification (looked up here: https://www.fortiguard.com/webfilter)
Kasperky wanted an account (and possibly a subscription) to look up the website and I'm not going to give them any of my information so I'm not sure if they gave an explanation as to why the website is flagged.
Visiting https://thisismyip.com/ as of now just redirects to a Namecheap landing page so I doubt there's any actual malware on the website. I think Fortinet and Kaspersky preemptively marked it for when a malicious actor picks up the name and starts hosting actual viruses.
We have a little one, in case it's useful. https://ip.brightfur.net/ Super simple. Works with curl too (autodetects whether to give you plain text or an HTML webpage).
It's like 20 lines of PHP and most of that's HTML.

i usually use icanhazip.com, seems to work well enough
ip.me also works well in the terminal with curl. The default response is plaintext
I always use check.torproject.org. If I'm not on Tor, it gives me my IP, if I am on Tor it verifies that. Good for both.
#!/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.
A simpler and easy to memorize alternative:
curl ifconfig.me
That still relies on an external website, whereas dig uses just DNS
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.
There is also ifconfig.me which works amazingly on the command like with curl ifconfig.me
At that point just run ifconfig
That's not how this works. That's not how any of this works.
exept it does? At least in ipv6 land
i could see a situation where a host that only speaks IPv4 would need to add my IP to an allow list, and therefore I would need to check what IPv4 address I appear as, even though I am running IPv6.
I wrote my own. It's one of the easiest possible services to write.
curl ifconfig.me
Not sure about Linux, but on a Mac you can put it on your clipboard with
curl ifconfig.me | pbcopy
xh ifconfig.me | wl-copy
👍
Oookay, I guess it detects the user agent and only sends the IP number when it detects curl. Using xh did not work as intended.
Huh. Is it going by user-agent or something? Weird.
Our own tiny one goes by the Accept header. If xh sets that to text/html you'll get an HTML webpage though.
Some sites go by that, some go by user agent. I believe xh can fake it's user agent, if I'm not mistaken.
A good compromise would be to go by known user agents, but also heed the accept header. 👍
