I'm seeing an IPv6 address that ends in :f68. Is shorthand for :0f68 or :f680? I'm trying to do a lookup on it and for some reason doesn't like the 3 digit segment.

Thanks!

:f68 expands to :0f68. The IP address components are hexadecimal numbers – only the leading zeros can be omitted. (See RFC 4291 section 2.2, "Text Representation of Addresses".)
