Summary

Surgutneftegas

Russian Federation · AI-generated

business oil gas corporate

SURGUTNEFTEGAS-AS is operated by PJSC "Surgutneftegas".

What it's used for

  • The address space carries corporate infrastructure, indicated by the netname Surgutneftegas-NET and the registrant Abuse-C Role.
  • The AS announces 512 IPv4 addresses across 1 prefix (95.181.146.0/23) and maintains 2 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of office workers and internal systems for a major Russian oil and gas company.

Notable

  • The RDAP registrant Abuse-C Role aligns with the announcer Surgutneftegas-AS and the registry holder PJSC "Surgutneftegas".
  • The address inventory is a single contiguous /23 block, typical of a dedicated corporate 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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
