Summary
IDNet
isp dsl broadband
A British ISP with 86 neighbours, a 1997 netname from a company it absorbed, and a customer's broadcast address named in full.
What it's used for
- Residential and business internet access. 20,992 addresses in six IPv4 prefixes, two IPv6 prefixes, and 86 observed BGP neighbours.
Notable
- The company's own netnames are dated:
UK-IDNET-990615inYYMMDD, then20040308,20061108and20080409inYYYYMMDD. 195.72.33.0/24is netnameUK-WORLDINTERNET-970609, registered to INDEXSCOPE LIMITED — a 1997 record for a company of a different name entirely.91.90.171.0/24belongs to VPW Systems (UK) Ltd, netnameVPWSYSUK-PD1, and its reverse names end.pd.vpwsys.net— the samePDas the netname.- One of those addresses is named
core-a-broadcast.pd.vpwsys.net. - Subscriber addresses read
cust255-dsl91-135-7.idnet.net.
Interesting
UK-WORLDINTERNET-970609is the oldest thing in this inventory by nearly two years, and it names neither the announcer nor the registrant. Three companies have touched that/24and the netname remembers the first.- Labelling a broadcast address by name, and marking the router as
core-a, is a hand-maintained zone. Nobody generatescore-a-broadcast; somebody typed it so that the next person to see the address in a log would not have to work it out. - 86 neighbours for 21,000 addresses is a British ISP that peers heavily, which is what the London exchanges made both possible and expected.

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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
