About this network

One contiguous block, one registration, twelve separate announcements.

What it's used for

• The corporate network of a Dutch bank. 8,192 addresses across twelve IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• Every prefix starts with 167.202. and every one carries the identical netname ABN-AMRO-BANK-N-V.
• The second registry contact on all twelve is SDM Infra Networks.
• The pieces are a /21, three /22s, four /23s and four /24s.
• Eighteen addresses were sampled and none returned a name.

Interesting

• Twelve announcements where one would do. The whole range is a single registration held by a single party, so the split is not about ownership; it is a network cut into per-site or per-function subnets, each announced separately so its path can be steered independently. A bank with geographically separated data halls has a concrete reason to want that.
• The cost is twelve entries in every routing table on the internet instead of one, which is the standing tension behind de-aggregation: the operator gets control and everyone else carries the weight.
• A second organisation appears on every block as infrastructure contact. Banks routinely outsource network operations while keeping the registration, and this is what that arrangement looks like from outside.
