Summary

Sweden · AI-generated

dns root infrastructure anycast

I-ROOT is operated by Netnod AB.

What it's used for

  • The space carries the I-root DNS service, as indicated by the AS handle I-ROOT and the registrant netname SE-RESILANS-20000317.
  • The AS announces 512 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a specialized infrastructure role rather than general transit or access.

Notable

  • The RDAP registrant for the announced prefix is Resilans AB, which differs from the registry holder Netnod AB.
  • Netnod has operated the i.root-servers.net DNS root name server since 2000, providing the service via a distributed anycast network.
  • The address inventory consists of a single IPv4 prefix (192.36.148.0/23) and a single IPv6 prefix (2001:7fe::/32).

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-12, 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: 435 networks and 1,769 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.
