Unclassified ARIN
Summary
Cloudflare
hosting infrastructure media
More IPv6 prefixes than IPv4 ones, hundreds of tiny slices, and not one address with a name.
What it's used for
- Part of a content delivery and security network. 61,184 addresses across 191 IPv4 prefixes plus 197 IPv6 prefixes, with 209 observed BGP neighbours.
Notable
- Every record checked carries the netname
CLOUDFLARENET, registered toCloudflare, Inc.with abuse, admin and operations contacts. - The IPv4 prefixes are almost all
/22s and/23s, spread across104.22,162.158,172.68,172.69and172.71. - The IPv6 prefixes are almost all
/48s under2400:cb00. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- The IPv6 count exceeding the IPv4 count is rare enough in this corpus to be worth stating plainly. Nothing else carded so far announces more of the newer protocol than the older one.
- Hundreds of
/22s and/23s rather than a few large blocks is what an anycast network looks like from outside. The same addresses answer in many places at once, and small pieces let each location be withdrawn or moved without touching the rest. - Not one sampled address has a name, across 388 announced prefixes. On a network where an address is a doorway to thousands of unrelated sites, a reverse name could not say anything true about who is behind it, so there is nothing useful to publish.
- 209 neighbours is the shape of a business that peers with everyone it can reach rather than buying its way to them.

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
225 upstream, 0 downstream and 442 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 2026-10-26, 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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
