AS13377 — RBB-ASN-1

AS13377 announces 1 IPv4 prefixes covering 1,024 addresses and 1 IPv6 prefixes.

About this network

A thousand IPv4 addresses next to an IPv6 block sized for a regional registry member.

What it's used for

• A small United States broadband provider. 1,024 addresses in one IPv4 prefix, 199.187.180.0/22, one observed BGP neighbour, and the IPv6 block 2604:8a0::/32.

Notable

• The AS handle is RBB-ASN-1 and the block's netname is ROGUE-BROADBAND.
• First observed in the routing archive in August 2005.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• The IPv6 allocation is the standard size a registry hands to any member that asks, regardless of how small the member is. Set against a thousand IPv4 addresses it is an enormous imbalance, and it is the ordinary state of affairs: IPv4 is rationed by scarcity and IPv6 by policy, and the policy is generous because the space is effectively unlimited.
• A single upstream means this provider's customers depend entirely on one transit relationship. For a network this size that is usually a cost decision rather than an oversight, since a second upstream costs about as much as the first.
• The -ASN-1 in the handle is a numbering scheme that anticipates a second autonomous system, and only one appears here.
