Summary
MSN Telecom (CEA)
isp business
Every sampled address answers, and one of them says it is leased.
What it's used for
- A small Russian provider network. 512 addresses in one IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.
Notable
- The entire inventory is
212.92.96.0/23, netnameRU-MCNTELECOM-19991103. - The AS handle is
CEA-AS, held by MSN Telecom LLC. - All three sampled addresses returned a name:
adr128.cea.ru,leased-255.cea.ruandemu-126.cea.ru.
Interesting
leased-255marks the address as let to somebody else. Address space is a rentable asset, and an operator with more of it than customers can sublet blocks the same way it sublets rack space. Writing that into the reverse name is unusually candid: most operators leave leased addresses looking exactly like their own.- Three sampled addresses, three different prefixes on the names —
adr,leased,emu— in a single/23. These names were assigned individually, by hand, over time, which is what happens on a network small enough that somebody knows what each address does. - The netname dates the block to 3 November 1999, in the same season as several other holders in this range. The company name in the netname,
MCNTELECOM, does not match the current holder'sMSN Telecom: one of them changed, and the registry kept the older spelling.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
