AS13511 — UNIVI-2-ASN

AS13511 announces 1 IPv4 prefixes covering 2,048 addresses and 0 IPv6 prefixes.

About this network

The netname is UNIVISION-IPV4-0, labelling the protocol version and numbering from zero.

What it's used for

• A broadcaster's network. 2,048 addresses across five IPv4 prefixes, six observed BGP neighbours, and no IPv6 announced.

Notable

• All five prefixes are netname UNIVISION-IPV4-0, registered to the company.
• The five are a /22 and the four /24s immediately after it, covering contiguous space.
• The AS handle is UNIVI-2-ASN.
• Fifteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Putting IPV4 in a netname only makes sense if you expect a matching IPv6 record. Somebody named this in anticipation of the other half, numbered it zero to leave room for a first and a second, and the company still announces no IPv6 at all. The naming outran the network.
• Announcing a /22 and the four /24s next to it, rather than the single /20 they would form, keeps each piece separately routable. For a broadcaster that means being able to move a service between providers without moving everything else with it.
• Six upstreams for 2,048 addresses is the connectivity profile of a company whose audience arrives in spikes around live events, buying more paths than the address count would suggest it needs.
