About this network

Everything about this record agrees with everything else, which is rarer than it sounds.

What it's used for

• A carrier's national arm. 1,024 addresses in a single IPv4 prefix, with one observed BGP neighbour and no IPv6 announced.

Notable

• The whole footprint is 209.46.48.0/22, carrying the netname RETN-US.
• Netname, registrant and AS name all say the same thing, with no spelling drift between them.
• The AS handle is truncated to RETN-, cut short by a length limit rather than by choice.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• After enough of these records, consistency stands out more than chaos. One netname matching one registrant matching one AS name, with a single block and no stray punctuation, means the whole thing was filed once by somebody who knew what it was for and has not needed touching since.
• The truncated handle is the only flaw, and it is the registry's rather than the operator's. Handles are capped at a length that was generous when it was chosen and now cuts names off mid-word, which is why so many entries in this range end in a dash.
• A carrier subsidiary appearing with one small block and one neighbour usually means the transit business itself runs under a different number, and this one exists to hold local address space and a corporate presence.
• Nothing published in reverse DNS on a carrier block suggests the space is assigned onward rather than used directly.
