Unclassified RIPE
Summary
Fujitsu Services (ICL)
enterprise legacy
ICLNET-AS — the corporate network of Fujitsu Services Ltd, the UK arm of Fujitsu. The handle is a fossil: ICL stands for International Computers Limited, the British computer manufacturer that Fujitsu absorbed and renamed Fujitsu Services.
What it's used for
- Fujitsu's own UK enterprise and IT-services network. It is a small, self-contained corporate estate, announcing only a pair of /23s.
Notable
- A textbook name fossil: the registry still says ICLNET decades after the ICL brand was retired. The AS number belongs to the acquiring company today.
- Do not read this as a UK service-provider network — it is Fujitsu's own corporate address space, not customer or hosting capacity.
Interesting
- The AS number is low and long-held, but the address block it announces (
185.13.48.0/22) is a much later RIPE allocation — a reminder that a legacy AS number says nothing about the age of the prefixes behind it.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
