Expressing IPv6 Addresses with Words
IPv6 addresses are 128-bit hexadecimal numbers, typically represented in eight groups of four hexadecimal digits separated by colons. Each group represents 16 bits, making the entire address 128 bits long. For example, an IPv6 address looks like this:
2001:0db8:85a3:0000:0000:8a2e:0370:7334
or in a shorthand notation:
2001:db8:85a3::8a2e:370:7334
For more details check our IPv6 Addressing Cheat Sheet.
To simplify IPv6 addresses and make them easier to read and remember, it's possible to express one or more 16-bit groups with words comprised of letter A - F (representing hexadecimal numbers) and commonly used number to letter substitutions:
- 0 to substitute for "O".
- 1 to substitute for "L" or "I".
- 2 to substitute for "R" or "Z".
- 5 to substitute for "S".
- 6 to substitute for "G".
- 7 to substitute for "T".
- 9 to substitute for "g" or "q".
For example:
2001:db8::dead:beef
2001:db8::bad:deed
2001:db8::g00d:f00d
2001:db8::de:caf:cafe
Note: Words longer that 4 characters must be split between two or more 16-bit address groups.
