Summary

Keyyo

France · AI-generated

telecom isp business

Four company names across handle, holder, netname and reverse zone, none of them agreeing.

What it's used for

  • A telephony and connectivity operator in France. 114,176 addresses across 33 IPv4 prefixes, sixteen IPv6 prefixes, and two observed BGP neighbours.

Notable

  • The AS handle is ASN-NERIM, the holder Keyyo SA, the netnames FR-PHONESYSTEMS-951127 and its dated siblings, and the reverse names end cust.keyyo.net or cnt.nerim.net.
  • Netname dates mix six digits (951127, 970523) with eight (20011003, 20110928).
  • Reverse names reverse the octets, as 254-175-79-194.cust.keyyo.net.
  • One name is cimchinonais-215-254.cnt.nerim.net, carrying a customer name instead.

Interesting

  • Every layer of this record was correct when it was written and they were written decades apart. Reading any single field gives a confident, outdated answer, which is why identification needs all of them together.
  • The customer-named reverse entry sits in a different domain from the generated ones, so hand-assigned and machine-assigned names live in separate zones. That is a tidier arrangement than the networks in this range that mix both in one place.
  • Sixteen IPv6 prefixes announced under a single /37 parent, each successive one twice the size of the last, is a range splitter's output rather than any human plan.

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.
