Summary

Internexus / Supanet

United Kingdom · AI-generated

isp residential legacy

Internexus Networks Limited is a UK ISP; its address space carries the Supanet and TalkGas consumer brands.

What it's used for

A retail access network. The AS announces ~24 IPv4 prefixes (~74k addresses), including the legacy 213.40.0.0/16, with three observed neighbours. Sampled reverse DNS is subscriber dial-up and ADSL naming: ip213040136000.adsl.supanet.net.uk and dynamic24001.dial.talkgas.net. This is consumer broadband and dial-up space.

Notable

  • The dial.talkgas.net and adsl.supanet.net.uk naming is a fossil of the UK's late-1990s/2000s dial-up and ADSL ISP era; the 213.40.0.0/16 block has been announced from this AS since 2000.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
