About this network

A netname numbered seven, on a university's only block in this AS.

What it's used for

• A university's network. 2,048 addresses in a single IPv4 prefix plus 2607:4000:300::/40 of IPv6, with one observed BGP neighbour.

Notable

• 173.250.224.0/21 carries the netname UW-SEATTLE-07, registered to the university with a security operations role contact.
• The AS handle is UW-GR-AS, with two letters in the middle that expand to nothing on their own.
• Three addresses were queried for reverse DNS and none returned a name.
• The AS first appeared in routing on 2000-08-18.

Interesting

• The number on the end says this is the seventh record in a series, and only one of them is here. A university of this size holds address space across several AS numbers, so an inventory built from one of them shows a fragment and the netname is what tells you so.
• Naming a security operations team as the registry contact is considered practice at institutions that receive a steady stream of abuse reports about student machines. Most organisations name a generic mailbox that nobody reads.
• A /40 of IPv6 is a large allocation, and universities were among the earliest adopters because research networks needed the space before anyone else did.
• One neighbour for a research institution is the shape of a campus that reaches the wider internet through a regional research network rather than by buying transit directly.
