A number that tells the internet where to send things. Every web page, email and video you ask for comes back to this address, the same way a letter comes back to your street address.

Your computer has a private address inside your home or office, usually starting with 192.168, 10 or 172. Your router shares one public address between every device behind it. This page shows the public one — the only one the rest of the internet ever sees.

IPv4 addresses look like 203.0.113.42. The world ran short of them, so IPv6 was made, with much longer addresses like 2001:db8::1. Many connections have both; this page shows whichever one your browser used to reach us.

Most internet providers lend you an address rather than giving you one to keep, and hand out a new one from time to time — often when your modem restarts. A phone gets a new one as it moves between towers and Wi-Fi. A fixed (“static”) address is usually an extra your provider charges for.

Yes. curl https://perrycs.com/ip prints just the address and nothing else, which makes it easy to use in a script.
