About this network

The only registrant on the block is a role whose name reads like a job title and a road.

What it's used for

• A software company's network. One IPv4 /24 announced from Austria, no IPv6, two hundred and fifty-six addresses, across two observed BGP neighbours.

Notable

• The block lists no company at all as registrant, only a role made of three words: two that name the person responsible for a host, and one that names a road.
• The netname is the brand and a country code, and the AS handle is the same two parts with the letters for an autonomous system added on the end, putting the country code in the middle.
• Two hundred and fifty-six addresses is the entire holding, and it has not changed since the routing archive began.
• Two upstreams for one block, which is one more than a network this size needs to function.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Role objects exist so that a network's contacts survive staff turnover: the block points at a role, the role points at whoever currently holds it, and the block never has to be edited. The side effect is a registry full of entries where the responsible party is a phrase rather than a name.
• A software company with its own number and one block is buying independence from its hosting provider. The addresses stay put when the contract changes, which matters when customers have them in firewall rules.
