About this network

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.
