Summary

Avast

Czechia · AI-generated

security enterprise business

AVAST-AS-DC is operated by Avast Software s.r.o., a Czech cybersecurity company.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS records pointing to ptr.avast.com and netnames such as CZ-ASW-20120525 and AVAST-COM.
  • The AS announces 5,632 IPv4 addresses across 15 prefixes and 6 IPv6 prefixes, while maintaining only 6 observed neighbours, indicating an internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of web and API endpoints for Avast's security software products, including updates, telemetry, and user-facing services.

Notable

  • Registrants align with the announcer, including AVAST Software s.r.o., Gen Digital Inc., and Privax LTD, reflecting the corporate structure and historical acquisitions.
  • The inventory includes legacy blocks from NortonLifeLock (now Gen Digital) and Privax, consistent with Avast's acquisition history and integration of acquired IP space.
  • The address inventory is finely subdivided into /23 and /24 blocks, supporting site-by-site segmentation within the corporate network.

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.
