Per-octet patterns (1, 2, 3, or 4 specify the octet; d, h or 0 specify decimal, hexidecimal, or 0-padded decimal)
First octet, decimal %1d 192
Third octet, 0-padded %30 023
Fourth octet, hexidecimal %4h 2d
All octets, different expansions %1h-%2d-%30-%4h c0-168-023-2d

%i and %r also allow explicitly defining the separator; eg %.i or %_r. '.', '-', and '_' are the only characters
supported since DNS names may not contain most other non-alphanumerics.
