About this network

The reverse DNS still belongs to a carrier that was bought and folded away long ago.

What it's used for

• A car dealership group's network. 512 addresses across two IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.

Notable

• 12.218.221.0/24 carries the netname GARBER-M24-221, ending with the block's own third number.
• 209.255.80.0/24 carries the netname 209-255-80-0, which is only the address.
• Three sampled addresses answer as 209-255-80-64.ip.mcleodusa.net and similar, under the domain of a carrier brand long since absorbed.
• Six addresses were queried for reverse DNS and three returned a name.

Interesting

• Reverse DNS is the slowest-moving record any network keeps. The carrier that owns this zone has changed hands and names more than once, and the hostnames still answer with the original brand, because nothing breaks if they do and somebody would have to choose to fix it.
• The two netnames are the two extremes of the same registry: one built from a template with the customer, a code and part of the address, the other consisting of nothing but the address.
• Three neighbours for a dealership group is more path diversity than most businesses this size buy, and it suggests locations connected through different providers.
• Dealer systems handle finance applications and identity documents for every customer who buys a car, which makes this an unremarkable network holding remarkable amounts of personal data.
