AS5500 CHESS Commercial Internet Service Provider
Residential RIPE
Summary
Chess ICT Ltd
isp enterprise legacy
CHESS is Chess ICT Ltd, a British business-communications and managed-IT provider based at Alderley Park in Cheshire. The RIPE record still describes it plainly as a "Commercial Internet Service Provider".
What it's used for
- Connectivity and hosted services sold to UK businesses: broadband and leased lines, VoIP and hosted telephony, mobile, and managed IT.
- The address space serves customer sites and Chess's own service platforms rather than a residential eyeball base.
Notable
- This is a business ISP, not a consumer one. Chess sells to SMEs and enterprises, so the routed space skews toward office sites, hosted voice and managed services.
- Chess is multi-homed through several UK and international transit providers and peers widely, which is typical for a mid-sized business operator that must keep customer circuits up.
Interesting
- The company grew out of the UK telecoms reseller market of the 1990s and later folded ICT and cloud services into the same business, which is why one AS carries both connectivity and hosted-application traffic.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,771 prefixes, as published 2026-10-15. 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.
