Unclassified RIPE
Summary
MegaFon
mobile telecom russia
MF-SIB-AS is operated by PJSC MegaFon, a major Russian mobile and fixed-line telecommunications provider.
What it's used for
- The address space carries mobile and data center traffic, evidenced by netnames such as
MF-SF-AS31205-MOB,MF-GDC, andMF-GDC-Yota-09112022. - With 19,712 IPv4 addresses announced across 26 prefixes and only 1 observed neighbour, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
Notable
- Registrants consistently identify as "Mobile; GNOC East PJSC MegaFon" or "MegaFon PJSC - Internet Service Network Operation Center," aligning with the AS holder.
- The inventory is finely subdivided into numerous /21, /22, and /24 blocks, reflecting internal segmentation for different service types and geographic regions within the corporate estate.

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 1,783 prefixes, as published 2026-10-17. 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.
