+  My IP answers the question "what's my IP address?"
+description: |
+  `myip` will contact ipify.org to tell you your IP addresses:
+
+    1. `api.ipify.org` for your IPv4 or A address
+    2. `api6.ipify.org` for your IPv6 or AAAA address
+---
+
+Example output:
+
+```txt
+IPv4 (A)   : 136.36.196.101
+IPv6 (AAAA): 2605:a601:a919:9800:f8be:f2c4:9ad7:9763
+```
+
+### What is an IP address?
+
+An IP or Internet Protocol address is basically the phone number of your
+computer or server.
+
+Whenever you visit a domain - such as https://google.com - the `google.com` part
+is _resolved_ to the IP address using, quite literally, the internet's Contacts
+list, known as DNS.
+
+### How to get your IP address?
+
+Due to how complex networking can be, the most reliable way to get your IP
+address is basically to "make a call" to another server and ask it to tell you
+what shows up on the "called id", as it were.
+
+_IPify_ is such a service.
+
+You likely have an IPv4 or A address as well as an IPv6 or AAAA address.
+
+To find out your IPv4 or A address:
+
+```bash
+curl -s https://api.ipify.org
+```
+
+To find out your IPv6 or AAAA address:
+
+```bash
+curl -s https://api6.ipify.org
+```
+
+To find out either address:
+
+```bash
+curl -s https://api46.ipify.org
+```
+
+You can also use the `ifconfig`, `ip`, or `ipconfig` commands to figure this
+out, but they may give you incorrect information if the network setup is complex
+(as is the case... most of the time - home and business networks, cloud
+networks, etc).
