Summary

ESET

Slovakia · AI-generated

security business slovakia

ESET-AS is operated by ESET, spol. s r.o.

What it's used for

  • The address space carries corporate infrastructure for the cybersecurity firm, evidenced by reverse DNS entries such as 91-228-165-255.ptr.eset.com and sk-ba-h1-gw-nat.eset.com.
  • The AS announces 2304 IPv4 addresses across 4 prefixes and 6 IPv6 prefixes, with 4 observed routing neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints, security product update servers, and administrative infrastructure for ESET's global operations.

Notable

  • Registrants for the majority of prefixes align with the announcer, listing ESET, spol. s r.o. for SK-ESET-NET and SK-ESETSK-20150402, while 38.90.226.0/23 is registered to Cogent Communications, LLC under netname COGENT-A.
  • The inventory is a finely subdivided corporate estate, with distinct netnames like SK-ESETSK-H7-2 reflecting internal site or function segmentation.

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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
