IPv6 lookup

Look up the network, validate the address and copy its compressed or expanded form.

Try an example2606:4700:4700::1111 2001:4860:4860::8888 2001:db8:0:0:1:0:0:1 ::ffff:192.0.2.128

Address formats

Compressed: 2606:4700:4700::1111
Expanded: 2606:4700:4700:0000:0000:0000:0000:1111

This address is not IPv4-mapped. There is no general conversion from an arbitrary IPv6 address to an IPv4 address.

Compress or expand an IPv6 address

An IPv6 address has eight 16-bit groups. Expanded notation shows all eight groups with four hexadecimal digits each. Compressed notation removes leading zeros and replaces a run of zero groups with ::.

Different text forms can identify the same address. Format validation does not establish assignment, reachability or a device’s physical location.

Can you convert IPv6 to IPv4?

An arbitrary IPv6 address has no equivalent IPv4 address. An IPv4-mapped address embeds an IPv4 value: ::ffff:192.0.2.1contains 192.0.2.1. This tool extracts that value; it does not translate a connection between IPv6 and IPv4 networks.
