About this network

A single /19 with nineteen BGP neighbours, and a street address where the AS name should be.

What it's used for

• A German business-internet and hosting provider. 8,192 addresses in one IPv4 prefix, one IPv6 prefix, and nineteen observed BGP neighbours.

Notable

• The entire IPv4 inventory is 212.11.224.0/19, netname DE-WORNET-19991013, registered to WorNet AG.
• IPv6 is 2a00:1278::/32.
• The AS handle is WORNET-AS Buergermeister-Graf-Ring 28.
• First observed in the routing archive at the earliest date the archive holds.
• Three addresses were sampled and none returned a name.

Interesting

• The handle carries a street address. This is the third holder in this range to put its postal location in the AS name field rather than in the address fields the registry provides for it, which suggests the practice was common enough at the time not to look odd to anyone filing.
• Nineteen neighbours against a single /19 is a lot of interconnection for a small allocation. Peering count tracks who a network talks to, not how big it is, and a provider selling connectivity to businesses buys reach rather than address space.
• 19991013 places the paperwork in October 1999, the same weeks as several other holders in this range across five countries. The registry appears to have processed applications in batches, so the date marks the day a clerk worked through a pile rather than the day this network was built.
