Summary

NextDNS

United States of America · AI-generated

dns cloud security content

NEXTDNS is operated by NextDNS, Inc.

What it's used for

  • The address space carries DNS resolution infrastructure, evidenced by reverse DNS entries like chi-1.edge.nextdns.io, lax-1.edge.nextdns.io, and dns2.nextdns.io.
  • The AS announces 2304 IPv4 addresses across 3 prefixes and 2 IPv6 prefixes, while maintaining 17 observed neighbours. This ratio of modest address space to a moderate number of peering partners indicates a content provider or service network rather than a transit carrier.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing nextdns, Inc. or NextDNS, Inc. for netnames NEXTDNS-US-01, US-NEXTDNS-20190624, and US-NEXTDNS-20211110.
  • The address inventory consists of two /22 blocks and one /24 block in IPv4, alongside two /33 IPv6 prefixes, representing a compact estate suitable for a global DNS service.

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

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
