AS12167 — LIGHTWAVE-DALLAS

AS12167 announces 3 IPv4 prefixes covering 1,280 addresses and 3 IPv6 prefixes.

About this network

A Dallas hosting and colocation provider.

What it's used for

• Customer hosting. 1,280 addresses over three prefixes, three IPv6 /48s, and thirteen observed BGP neighbours.

Notable

• Thirteen neighbours against 1,280 addresses is a lot of interconnection for a small footprint, which is what selling colocation in a carrier-dense market looks like.
• The three IPv6 /48s come from two different /32s — 2606:b600 and 2607:6b80 — rather than from one allocation.
• Reverse DNS uses two different schemes at once. Names in 104.232.32.0/23 spell the whole address, host104-232-32-128.lightwavenetworks.com, while names in the 107.161 blocks use the last octet only, host128.lightwavenetworks.com.

Interesting

• The short scheme cannot survive the network it is in. Last-octet-only names give 256 possibilities across prefixes holding 1,280 addresses, so it runs out four times over. The longer form in the other block is the same idea done after someone noticed.
• Dallas is one of the handful of US cities where a small provider can reach a large number of networks without buying long-haul capacity. The thirteen neighbours are less a property of this company than of the building it is in.
