Summary

FirstDC

Russian Federation · AI-generated

hosting datacenter russia

BIG-AS is operated by FirstDC (Perviy TSOD LLC).

What it's used for

  • The address space carries datacenter and virtualization infrastructure, evidenced by netnames FIRSTDC-NET and VIRTY-IO associated with registrants OOO Pervyi TsOD and Perviy TSOD LLC.
  • The AS announces 9,472 IPv4 addresses across 15 prefixes with only 1 observed neighbour, indicating a hosting or datacenter role rather than transit.
  • Traffic from this AS consists of web hosting, virtual private servers, and cloud services provided by FirstDC, a Russian datacenter operator.

Notable

  • Registrants consistently identify as Perviy TSOD LLC or OOO Pervyi TsOD, aligning with the AS holder BIG-AS Perviy TSOD LLC.
  • The inventory is fragmented into multiple /24 and /22 blocks, including legacy ranges like 193.233.32.0/20 and newer allocations such as 185.144.114.0/24.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
