Summary

Fastnet LLC

Russian Federation · AI-generated

business russia small

AS51410 is operated by Fastnet LLC.

What it's used for

  • The address space is registered under the netname meganetwork with registrant MEGANET-2003 NOC; Meganet-2003 LLC, indicating the space is associated with Meganet-2003 LLC.
  • The AS announces 256 IPv4 addresses in a single /24 prefix and 1 IPv6 prefix, with 2 observed routing neighbours. This small inventory and low neighbour count suggest a limited-scale business or internal network rather than a large access or transit provider.

Notable

  • The RDAP registrant for the announced prefix is MEGANET-2003 NOC; Meganet-2003 LLC, which differs from the AS holder Fastnet LLC. This discrepancy may indicate leased space or a corporate relationship between the two entities.
  • The address inventory consists of a single contiguous IPv4 block and one IPv6 prefix, representing a compact and simple allocation.

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 1,781 prefixes, as published 2026-10-16. 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.
