About this network

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.
