AS15466 — ASN-DTO Maasland Netherlands

AS15466 announces 2 IPv4 prefixes covering 5,120 addresses and 1 IPv6 prefixes.

About this network

Fifty-two neighbours for five thousand addresses, which is not how a government network usually connects.

What it's used for

• A state materiel and information technology command. Two IPv4 prefixes and one IPv6 /36 announced from the Netherlands, five thousand addresses, across fifty-two observed BGP neighbours.

Notable

• The two IPv4 blocks are a /20 and a /22 from unrelated parts of the address space, with allocation dates in their netnames eighteen years apart.
• The AS handle carries a town name and the country, which is more geography than these fields normally hold.
• Both blocks list the same two registrants: a management role for registry work, and the command itself.
• The IPv6 prefix is far larger than the IPv4 holding, which is normal, since address scarcity does not apply on that side.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Fifty-two neighbours is the number that stands out. That is more interconnection than most networks ten times this size carry, and it means traffic reaches here by many independent paths.
• An eighteen-year gap between allocations says the original block sufficed for most of the network's life, and something changed recently enough to need more.
• Nothing published in reverse across five thousand addresses is a defensible choice for an organisation that would rather not have its internal structure read out of DNS.
