IPv6 Address Compressor
Paste any full IPv6 address to instantly compress it to the shortest valid representation using zero suppression and consecutive group elimination. View the shortened IPv6 notation alongside the original expanded form — perfect for simplifying addresses in DNS records, firewall rules, and network configurations. The ipv6 subnet calculator accepts any IPv6 address and prefix length and outputs the network address, address range, and total count.

How IPv6 Compression Works
Rule 1: Remove Leading Zeros
Each group of 4 hex digits can have leading zeros removed:
Before: 2001:0db8:0001:0042
After: 2001:db8:1:42
Rule 2: Use :: for Consecutive Zeros
One sequence of consecutive all-zero groups can be replaced with ::
Before: 2001:db8:0:0:0:0:0:1
After: 2001:db8::1
