About this network

A support queue named as the registry contact, which is better than most alternatives.

What it's used for

• A technology company's network. 1,024 addresses in a single IPv4 prefix, with two observed BGP neighbours and no IPv6 announced.

Notable

• The whole footprint is 199.7.240.0/22, carrying the netname VLABS.
• The netname and the AS handle are the same five letters, an abbreviation of the company name.
• The contact on the record is a customer support queue rather than a named person.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Pointing the registry at a support queue is an unglamorous choice that works. A queue outlives employees, gets read on weekdays, and turns an abuse report into a ticket somebody has to close. The alternative, a person who left in a previous decade, is far more common in records this old.
• One block from a range issued when a thousand addresses were routine, held ever since, with no second allocation and no IPv6, describes a company whose network requirements settled early and never changed.
• Two upstreams is the smallest arrangement that justifies running an AS at all, and it is what most organisations this size settle on.
• Nothing published in reverse DNS means the addresses are used rather than advertised. A scan finds live space and learns nothing about what it is for, which is the outcome the operator would want.
