Summary

Digiweb

Ireland · AI-generated

residential isp broadband ireland

DIGIWEB-AS is operated by Digiweb ltd, an Irish telecommunications provider.

What it's used for

  • The address space carries residential and metro broadband traffic, evidenced by reverse DNS entries such as ip-84-203-64-0.broadband.digiweb.ie, ip-78-137-175-254.dsl.digiweb.ie, and ip-83-147-175-254.clw.metro.digiweb.ie.
  • The AS announces 199,424 IPv4 addresses across 44 prefixes and 13 IPv6 prefixes, while maintaining 605 observed neighbours; this high neighbour count relative to the address inventory indicates a transit or peering-heavy role rather than a pure access network.

Notable

  • All sampled registrants are listed as "Digiweb Network Engineering; Digiweb ltd", which aligns with the AS holder and confirms consistent ownership of the announced space.
  • Digiweb is also known as Viatel Ireland, a name referenced in peering databases, reflecting the company's branding or corporate structure.
  • The inventory includes a mix of large /16 and /18 blocks alongside numerous smaller /20 and /22 prefixes, suggesting a segmented allocation strategy for different service tiers or geographic regions.

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 1,771 prefixes, as published 2026-10-15. 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.
