dns security business anycast

The AS handle DNSFILTER-AS-AP is held by DNSFilter, Inc.

What it's used for

  • The address space carries DNS security infrastructure, evidenced by the netname DNSFILTER-AP on three prefixes and the reverse DNS entries pointing to ptr.anycast.net for the 45.54.28.0/24 block.
  • The AS announces 1536 IPv4 addresses across 4 prefixes and 3 IPv6 prefixes, with 4 observed neighbours, indicating a small, focused network rather than a transit or large access provider.
  • Traffic from this AS consists of DNS queries and responses for DNSFilter's filtering service, which protects organizations from malware, phishing, and unwanted sites.

Notable

  • Registrants for the 103.85.42.0/23, 103.247.36.0/23, and 45.253.131.0/24 prefixes are listed as DNSFilter Inc administrator or DNSFilter, Inc., while the 45.54.28.0/24 prefix is registered to NetActuate, Inc.
  • The address inventory is small and subdivided, with three prefixes under the DNSFILTER-AP netname and one under NETACTUATE-IPV4, suggesting a mix of owned and leased or partner space for their anycast DNS service.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 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.
