Summary
CIRA
registry anycast infrastructure business
CIRADNS3 is operated by CIRA Canadian Internet Registration Authority.
What it's used for
- The address space carries registry infrastructure, specifically identified by the netname
CIRA-ANYCASTfor both announced IPv4 blocks. - The AS announces 512 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with 3 observed routing neighbours.
- Traffic consists of anycast services for the .CA domain registry, including DNS resolution and related internet performance solutions.
Notable
- Registrants for both prefixes match the announcer, listed as CIRA Canadian Internet Registration Authority.
- The inventory consists of two contiguous /24 IPv4 blocks and two /48 IPv6 blocks, forming a compact anycast footprint.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
3 upstream, 0 downstream and 6 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 442 networks and 1,773 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.
