About this network

154,880 addresses in fifty-four separate announcements, and not one IPv6 route.

What it's used for

• The mobile network of an Irish operator. 154,880 addresses across fifty-four IPv4 prefixes, eighteen observed BGP neighbours, and no IPv6 announced.

Notable

• The largest blocks are 92.251.128.0/17, 31.200.128.0/18 and 178.167.128.0/18.
• Netnames mix dated and undated forms: IE-H3G-20060504, IE-H3G-20071123, IE-H3G-20100317, IE-H3G-20110428, H3G-IE and H3GIE-SUBS3.
• Every block lists role objects named ROI Admin and ROI Tech.
• Sampled names read 92.251.160.0.threembb.ie, the four octets written forward with no separator before the domain.

Interesting

• A handset network of this size with no IPv6 route at all is the most expensive way left to run a mobile operator. Every subscriber has to be squeezed behind shared addresses, and the fifty-four fragments are the record of buying more IPv4 in whatever pieces were available, year after year.
• The reverse names are an address with a domain glued to the end, so the hostname reads like a sentence that changed its mind. It parses fine and it carries no information the address did not already carry.
• SUBS3 in one netname marks a subscriber pool, and the numbered suffix implies at least two others before it. The registry is being used as an internal inventory of pools here, not just as a record of who holds what.
