AS15220 announces 3 IPv4 prefixes covering 768 addresses and 0 IPv6 prefixes.

About this network

One netname ends in the number of the AS that announces it.

What it's used for

• Three IPv4 /24 blocks announced through a single observed BGP neighbour. The holder lookup failed, so nothing can be said about who the number is assigned to.

Notable

• Two netnames share a prefix naming a hosting provider, a three-letter site code and a customer, and differ only in the number on the end. One of those numbers is this AS number itself.
• The third block carries an unrelated netname of three letters and a country code.
• The AS handle is a reserved placeholder rather than a name, the third such handle in this range that is announcing routes.
• Nine addresses were queried for reverse DNS and none returned a name.
• The routing history begins in 2001, later than most of its neighbours in this range.

Interesting

• A netname containing the AS number is the closest thing in these records to a cross-reference. It was almost certainly typed by hand, from a ticket that mentioned both, and it works: the label ties the block to the routing in a way no field is designed to.
• The other number in the matching netname is not an AS number at all, which is the problem with conventions that emerge rather than get specified. Two labels that look alike mean different things.
• Three blocks from two providers, a failed holder lookup, an unknown country and no reverse names. What is visible is a customer identified only by a code inside somebody else's naming scheme.
