About this network

Five blocks collected one at a time over a decade, one of them registered on the last day of a year.

What it's used for

• A rural broadband provider. Five IPv4 prefixes and one IPv6 /32 announced from Ireland, four thousand addresses, through one observed BGP neighbour.

Notable

• Every netname follows the same pattern of country code, a four letter abbreviation of the company, and the allocation date, so the set reads as a timeline.
• Those dates are spread across more than a decade, and one of them falls on the final day of its year.
• All nine answering addresses use one form: the full address with dashes under the company's domain.
• Fifteen addresses were queried for reverse DNS and nine returned a name.
• One observed neighbour carries all four thousand addresses.

Interesting

• Acquiring address space in small pieces years apart is what a growing rural provider does. Each block is a round of subscribers that the previous block could no longer hold.
• Naming every address the same way is the practical choice for a network whose customers are homes. The name identifies the line without identifying the household.
• The single upstream is the real constraint. A provider serving a region with one path out has no answer to that path failing, and rural networks are where that hurts most.
