business cloud vpn infrastructure

COFRACTAL-001 is operated by Cofractal, Inc.

What it's used for

  • The address space carries corporate and cloud infrastructure, evidenced by reverse DNS entries such as unused.net.cofractal.com, cfe.net.cofractal.com, and nat64xlat-cust.net.cofractal.com.
  • One prefix, 44.4.41.0/24, is registered to Amateur Radio Digital Communications with the netname AMPRNET, indicating a specific allocation for amateur radio digital communications.
  • The AS announces 4864 IPv4 addresses and 94 IPv6 prefixes, with 24 observed neighbours, suggesting a business or infrastructure provider rather than a large residential access network.

Notable

  • Registrants for most prefixes are Cofractal, Inc., with netnames like OBJECT-CFRCTL-E6991521-8FAE-463E-BD78-EC5428A32D3D, 610, CFR1, C3, and CF64-4.
  • The prefix 44.4.41.0/24 is registered to Amateur Radio Digital Communications, distinct from the primary holder.
  • The inventory includes a mix of /22, /23, and /24 IPv4 blocks, along with a substantial IPv6 allocation under 2600:ec00::/31 and 2600:ec02::/40.

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: 436 networks and 1,771 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.
