Residential RIPE Cable/DSL/ISP
Summary
GCI Network Solutions (Nasstar)
enterprise isp legacy
EDGE / "ta GCI Com" is GCI Network Solutions Limited, the UK managed-services and business-connectivity operator that now trades as Nasstar. The handle is a fossil of the Edge Telecom lineage the AS came in on.
What it's used for
- Business connectivity and managed IT for UK corporate and public-sector customers. The sampled reverse names are unmistakably B2B access rather than consumer broadband:
ecc-customer.router.eclipse.net.uk(a customer edge router) and static-DSL naming in theuk.dsl.sta.u.tvzone — note thesta, for static.
Notable
- The inventory reads as an accretion of absorbed UK ISPs. The reverse-DNS zones carry the names of Eclipse Internet and UTV Internet (
u.tv), two operators whose business bases were rolled up through the KCOM/GCI/Nasstar chain of acquisitions — the addresses moved but the zones never got renamed. - Announced space is highly fragmented — dozens of /24s and /22s spread across several unrelated legacy RIPE ranges (
62.x,86.54.x,194.46.x,217.154.x,213.218.x). That scatter is inherited from the acquisitions, not assembled. - Card the network, not the brand: a name-only read of "GCI" or an eyeball-ISP reverse name would file this as consumer broadband. The static-DSL and customer-router naming says otherwise.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
