IPv6

128-bit addresses represented in hexadecimal notation, separated into eight sub-blocks of 16 bits each.

Compression

1. Zero Compression: If an IPv6 address contains continuous zeros, they are replaced with a double colon ”::“. ef82:0000:0000:0000:0000:1a12:1234:1b12 → ef82::1a12:1234:1b12
2. Leading Zero Compression: 1234:0fd2:5621:0001:0089:0000:0000:4500 → 1234:fd2:5621:1:89:0:0:4500
