About this network

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 Reading any single field gives a confident, outdated answer, which is why identification needs all of them together.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.
