IPv6 Expand & Compress

Expand an IPv6 address to all 32 digits, or compress it (RFC 5952).

About IPv6 Expand & Compress

Convert IPv6 addresses between the full form with every zero and the short canonical form used in configuration files – for one address or a whole list.

How to use

  1. Type an IP address, host name, domain or coordinates – or use the values filled in for you.
  2. Press Enter or the button – results appear instantly, and the page link keeps your query for sharing.
  3. Click any value to copy it; tables can be sorted and exported as CSV or JSON.

WhereNex does not store the addresses, names or positions you look up. IP locations come from our own copy of the DB-IP database (CC BY 4.0) and are approximate.
