Turn an IPv6 address into a bare 32-digit hex string, 0x literal and reverse-DNS nibble format.
A flat hex string is the form used by databases, TCAM entries and log pipelines. Reverse DNS uses the same digits in reverse order, one nibble per label. PTR records for IPv6 are painful to build by hand, and a single transposed nibble makes reverse lookups fail in ways that are hard to spot.
IPv6 Hex
The eight groups are concatenated into 32 hex digits; reversing the digits and joining them with dots gives the ip6.arpa name.
