Oh no, this has been my go-to site for connectivity tests (as example.com seems to be cached fairly aggressively by my browsers and that has misled me in the past). Ad-free, minimal, does exactly what it needs to and nothing more. Rest in peace! Edit: All these (great and much appreciated!) responses of alternatives are making me wonder if this should in fact be a standardized service that could then be offered as a public good in a similar way as pool.ntp.org. Checking for generic Internet connectivity (i.e. not only having an IP address, but being able to reach public sites, these sites being non-cached, not-captive-portaled etc.) seems like a problem that too many apps, scripts, and devices are solving again and again.

If you have the resources to maintain it, you can contact the estate. (They'd like to sell the domains, so unless they're bundled with Brickshelf the highest bidder will probably be a traffic-farming company or something, but you never know.)

ifconfig.me is a similar service which I often use. It has a nice feature that if you do "curl ifconfig.me", you'll get only a string with the ip address, no markup.

  Me too, but that's a whopping 5 characters more. Think of all the extra keyboard wear! I do like the curl-ability of that one a lot, though, and on my own computer I can just configure an alias or shell function for it :)

    Try "curl ip.wtf" to save your keyboard :)

  This site is behind cloudflare and has captcha-blocked my queries more than once.

    ifconfig.me is not behind Cloudflare, at least currently.

  On a Reddit post, someone mentioned ip.wtf that they created as a similar service. Aside from using it in a browser, it also provides a single IP address with curl ip.wtf, with less typing. I also like getting more information by using this: curl --json "" ip.wtf

I've been using ipinfo.io now for several years and have been very pleased with them. You can `curl https://ipinfo.io/ https://ipinfo.io/` and get a JSON blob back with info on your current IP. If you pass an IP explicitly you can get info back on it, for example `curl https://ipinfo.io/104.26.7.98 https://ipinfo.io/104.26.7.98`. Easy to combine with jq also for use in scripts: `curl https://ipinfo.io/104.26.7.98 https://ipinfo.io/104.26.7.98 | jq -r '.ip'` For personal use it's free, and they have reasonable pricing for large volume. No affiliation on my part, just a happy user.

  `curl https://myip.wtf/json https://myip.wtf/json` too is nice to use when debugging things
  - stevenkillian 2y ago
    Also protocol specific hosts: https://json.ipv4.myip.wtf/ https://json.ipv4.myip.wtf/ https://json.ipv6.myip.wtf/ https://json.ipv6.myip.wtf/ https://json.myip.wtf/ https://json.myip.wtf/

  Annoyingly, they no longer show your IP on their web homepage.
  - reincoder 2y ago
    We are experimenting with some design choices as we try to highlight all the IP metadata we have and move towards being an "internet data" company instead of just an IP location company. I highly recommend you check out the page: https://ipinfo.io/myip https://ipinfo.io/myip I understand the data we have for your IP address is not front and center anymore. We have gone through several iterations of designs for our homepage, so if you have any suggestions, I will relay them to our team.

I use ip.me it's not add free, but in curl you can have an ad free version by doing curl -4 ip.me or curl -6 ip.me since it will only send the ip when it detects curl I guess.

  I was recently looking for IPv4/IPv6-only HTTP services hosted by major CDNs (for https://github.com/pmarks-net/ipvfoo/issues/60 https://github.com/pmarks-net/ipvfoo/issues/60), and found these: Cloudflare: https://ipv4.icanhazip.com https://ipv4.icanhazip.com + https://ipv6.icanhazip.com https://ipv6.icanhazip.com Akamai: https://ipv4.whatismyip.akamai.com https://ipv4.whatismyip.akamai.com + https://ipv6.whatismyip.akamai.com https://ipv6.whatismyip.akamai.com The problem with https://checkip.amazonaws.com https://checkip.amazonaws.com is that it neither supports IPv6, nor claims that it will remain IPv4-only, so it's not clear what you'll get in the future.

  That’s a lot worse to type, but good to know.

For services like this, I always use my own domain which can easily be re-mapped or hosted myself. E.g. "checkip.mydomain.com"

You can also use dig to get your external ipv4. That prevents reliance on smaller sites Don’t have the command on hand but easily searchable
- lxgr 2y ago
  How so? Getting your public/external IP does not seem possible behind a NAT without an external service.
  - Havoc 2y ago
    No idea. All I can tell you is that it works and if I need to hard code a IP check like this then I’d rather rely on a big player like Google or cloudflare ns than someone’s project site
    - Sophira 2y ago
      What command line do you use?
      - Havoc 2y ago
        dig whoami.cloudflare ch txt @1.1.1.1 +short
    - lxgr 2y ago
      Not sure if I'd trust an undocumented Google feature without any SLA more, to be honest. Rumor has it that Google have discontinued a service or two before.
  - speleding 2y ago
    You can use dig: dig +short -4 myip.opendns.com @resolver1.opendns.com (still an external service, but not reliant on a website)
    - lxgr 2y ago
      That's just another protocol in the end (DNS vs. HTTP), or am I missing something? DNS also runs a higher risk of being cached or mangled somewhere along the way by middleboxes. HTTPS avoids that problem.

ip.guide is also a great one. Provides a json payload with relevant information. I have no affiliation with it, just happy user!
