Unclassified RIPE
Summary
MegaFon
mobile telecom access russia
MF-KAVKAZ-AS is operated by PJSC MegaFon, a major Russian telecommunications provider.
What it's used for
- The address space carries mobile and fixed-line services, evidenced by netnames such as
RU-MEGAFON-20110404andMF-KAVKAZregistered to MegaFon's Network Operation Centers. - The AS announces 64,000 IPv4 addresses across 66 prefixes and 9 IPv6 prefixes, while maintaining only 9 observed neighbours, a ratio characteristic of an access network serving end-users rather than a transit provider.
Notable
- Registrants consistently identify the holder as MegaFon, with specific branches like the "Caucasian Branch of PJSC MegaFon NOC" and "GNOC East PJSC MegaFon" listed for various blocks.
- The inventory is finely subdivided into numerous /20, /21, and /22 blocks, reflecting site-by-site segmentation typical of a large internal corporate estate managing regional mobile infrastructure.

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.
