What it's used for
- The address space carries residential fibre-to-the-premises traffic, evidenced by the reverse DNS record
cust-185-20-54-254.fttp.tel.uk.as61049.netand netnames such asUK-EXASCALE-20130301andUK-EXASCALE-20170321. - The AS announces 5120 IPv4 addresses across 11 prefixes and 12 IPv6 prefixes, while maintaining 1011 observed neighbours; this high neighbour-to-address ratio indicates a transit and peering role alongside its access network.
- Traffic from this AS consists of subscriber eyeballs for multi-gig full fibre broadband services, with speeds up to 2.5Gbps, delivered via Openreach and CityFibre networks across the United Kingdom.
Notable

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: 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.
