About this network

Four upstreams for a network that fits in two blocks.

What it's used for

• An investment company's network. 1,280 addresses across two IPv4 prefixes, with four observed BGP neighbours and no IPv6 announced.

Notable

• 66.45.80.0/22 and 66.151.51.0/24 both carry the netname XVL, which is also the AS handle.
• Both are registered directly to the company with no role contact named.
• Six addresses were queried for reverse DNS and none returned a name.
• The AS first appeared in routing on 2000-08-18.

Interesting

• Four upstream relationships is a lot for this much address space. Networks connect to that many carriers when the traffic is worth protecting rather than when there is a lot of it, so what runs on these addresses is something that must not go down rather than something large.
• An AS registered to an investment vehicle usually means acquired businesses. Firms that buy small software companies inherit their networks, and the address space tends to be consolidated under the parent's name while the systems using it stay where they were.
• Three initials used as handle, netname and nothing else gives a reader no way to tell what runs here. Combined with the silence in reverse DNS, this is a network that publishes the minimum the registry demands.
• The two blocks come from ranges that are close together but not adjacent, so they need separate announcements.
