About Network Tools
Networking formats routinely use hexadecimal for compactness. This category converts IP addresses and MAC addresses to and from hex — the representations you'll see in routing tables, firewall rules, and packet captures.
Frequently Asked Questions
Why do routers show IP addresses in hex?
Hex is a compact, fixed-width way to represent the 32-bit IPv4 address space, which is easier to scan in logs and configuration files than four separate decimal octets.
How is a MAC address related to hex?
A MAC address is just 6 bytes, conventionally written as 12 hex digits separated by colons or hyphens.
