Summary

isp residential uk small
The AS handle LGB-AS is held by Luke Eiji Granger-Brown.
What it's used for
- The address space carries residential or small-business internet access, indicated by netnames
LGB-BLADENETandLGB-WGand reverse DNS entries pointing toptr.as205479.net. - The AS announces 512 IPv4 addresses across 2 prefixes and 7 IPv6 prefixes, while maintaining 77 observed neighbours; this high neighbour-to-address ratio indicates a transit or peering-heavy role rather than a large access network.
- Traffic from this AS consists of subscriber internet access for a regional cable/DSL/ISP operation in the United Kingdom.
Notable
- Registrants for the announced prefixes are listed as
Abuse-C Role, which aligns with the individual holder identity. - The address inventory is small and finely subdivided, with two /24 IPv4 blocks and multiple /48 and /32 IPv6 prefixes, consistent with a small-scale independent ISP.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
