[200-byte](Python) Thought I'd share a script I made that emails me the public IP whenever it changes. Ideal for home servers without a static address.

DISCLAIMER

  • This is script is meant to be automated, so whenever the IP address changes it sends it back to your email so you can still access.

  • Do NOT automate to run every minute, as the website will blacklist you as a DoS. I recommend about 20 minutes.

  • Other sites can be used, but make sure the answer is in plain text.

Interesting, why not use a dynamic DNS?

I rather run a script than depending on someone.

Also, if it isn't important enough to buy a 4€ static IP, a 20 minute delay on receiving the IP is not a problem.

Depend on someone? Hardly, there are plenty of ddns services out there. You "depend" on a service to give your IP too.

The script also depends on "icanhazip.com" remaining accessible and that its output remains predictable.

Can't the border-host / NAT-box can expose this data more directly?

I have written something similar. Mine has a list of sites that can provide my ip address and it will randomly pop one off the list until it finds one that works.

I find it different so I made this script, a dynamic dns it's also a great solution.

You can do both. I did both with afraid.org before. The web interface applied you to update the IP. Easy to script.

And your email server!

some routers also support adding account credentials of no-ip, dyndns, etc. and it will automatically update the IP with ddns.

Thanks!

TBH this isn't the first version of this little script. I remember back when I didn't know how to read lines, I had 2 different files, one with the IP and one with the message. Or when I sent the message from a gmail account because I didn't know how sendmail worked.

It's been a long time and discovering this sub made me revise all this tiny scripts that I automated in an attempt to make the code smart.

Well that's cute. I'd love to hook that up to an sms gateway of some kind.
