How it works
This page validates a standard IPv6 address and expands it into exactly eight groups, each padded to four hexadecimal digits.
Examples
- 2001:db8::ff00:42:8329 → 2001:0db8:0000:0000:0000:ff00:0042:8329
- ::1 → 0000:0000:0000:0000:0000:0000:0000:0001
- fe80::202:b3ff:fe1e:8329 → fe80:0000:0000:0000:0202:b3ff:fe1e:8329
