About Your IP Address
Your IP (Internet Protocol) address is a unique number that identifies your device or network on the internet. Every time you visit a website, your public IP is shared so the server knows where to send the response.
IPv4 vs IPv6
IPv4 addresses look like 203.0.113.42 and are the most common. IPv6 addresses are longer (e.g. 2001:db8::1) and were introduced because the world ran out of available IPv4 addresses.
What is Reverse DNS?
Reverse DNS (a PTR record) maps an IP address back to a hostname. It's commonly used by mail servers to verify the identity of a sender and reduce spam.
