Unclassified ARIN
Summary
RETN US
transit telecom business
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 netnameRETN-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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
