Summary

Interfonica

Russian Federation · AI-generated

isp russia business

INTERFONICA is operated by Interfonica LLC.

What it's used for

  • The address space carries business and enterprise traffic, evidenced by netnames RU-INTERFONICA-20180118 and INTERFONICA associated with registrants INTERFONICA LLC and Net Atelye Ltd.
  • The AS announces 1536 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 3 observed neighbours, indicating a small-scale access or business network rather than a transit provider.
  • Traffic from this AS consists of corporate and business users, given Interfonica's role as a Russian telecommunications provider.

Notable

  • Registrants align with the announcer, with INTERFONICA LLC holding the primary prefix and Net Atelye Ltd. holding the secondary prefix.
  • The address inventory is compact, consisting of one /22 and one /23 block, with no significant anomalies in the prefix structure.

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 1,784 prefixes, as published 2026-10-19. 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.
