AS13837 — POINT5-MS

AS13837 announces 4 IPv4 prefixes covering 1,280 addresses and 1 IPv6 prefixes.

About this network

Four blocks from four unrelated ranges, all registered under one netname.

What it's used for

• A managed services provider. 1,280 addresses across four IPv4 prefixes, the IPv6 block 2605:ff40::/32, and eight observed BGP neighbours.

Notable

• The prefixes begin 147.185, 137.83, 192.197 and 206.166, sharing no common parent.
• All four are netname PMSL-17, the company's initials and a number.
• All four are registered to the company directly rather than to a carrier.
• Eight upstreams serve 1,280 addresses.
• Twelve addresses were queried for reverse DNS and none returned a name.

Interesting

• Four blocks from four separate ranges is what buying address space on the transfer market looks like. Nothing about the numbers relates them; the only thing they have in common is who owns them now, and the shared netname is the registry recording exactly that.
• One netname across all four makes the registry unable to tell them apart, which matters more here than in a carrier's records, because these came from different places and may have different histories attached to them.
• Eight upstreams for a network this size is a provider selling reachability rather than capacity: the paths are the product, and a /32 of IPv6 costs nothing to hold alongside them.
