Extra icanhazip services going offline

Every great thing has its end, and the extra services I launched along with icanhazip.com are no exception. I started icanhazip.com way back in 2009 and detailed much of the history when I transferred ownership to Cloudflare.

The extra services, such as icanhazptr.com, icanhaztrace.com, and icanhaztraceroute.com, came online in 2013 and they weren’t part of the Cloudflare transfer. These services add extra challenges since they need IPv6 connectivity and they don’t play well with containers. Relative to icanhazip.com, these services receive very little traffic.

As much as I’d like to keep running these sites, the extra services will go offline on August 17, 2022.

And if you can’t live without it #

Still need PTR record lookups and traceroutes on your network? All of the code is on GitHub in major/icanhaz. To run it, simply execute the icanhaz.py script on your machine.

You can also use gunicorn with a command like this one:

gunicorn icanhaz:app

You can also get very fancy with a systemd unit that exposes a UNIX socket:

[Unit]
Description=Gunicorn instance to serve icanhaz
After=network.target

[Service]
User=nginx
Group=nginx
WorkingDirectory=/opt/icanhaz
ExecStart=/usr/bin/gunicorn --workers 4 --bind unix:icanhaz.sock -m 007 icanhaz:app

[Install]
WantedBy=multi-user.target

And then configure nginx to serve traffic from the socket:

server {
	listen       80;
	listen       [::]:80;
	server_name  _;
	root         /usr/share/nginx/html;


	location / {
		proxy_set_header Host $http_host;
		proxy_pass http://unix:/opt/icanhaz/icanhaz.sock;
	}
}

Thanks for all the support over the last 13 years! 🫂
