Network type: hosting

AS13852 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

One source calls this AS reserved while it is announcing a block from the other side of the world.

What it's used for

• A casino operator's network. 256 addresses in the single IPv4 prefix 203.10.122.0/24, one observed BGP neighbour, and no IPv6 announced.

Notable

• The registry holder record names the company and gives the handle AS-PCI-01.
• The inventory's AS handle field instead reads -Reserved AS-, hyphens included.
• The announced block sits in a range administered by another region's registry, while the company and its routing are American.
• The block is netname PC-115, initials and a number, registered to the casino operator.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Two sources disagreeing about whether an AS number is assigned or held back is the sort of gap that makes automated trust decisions hard. The number is plainly in use, so the reserved marker is stale data being served with as much confidence as the live record beside it.
• A block from another region's range announced by an American company usually arrived through a transfer, which is exactly what the registries built transfer processes to record. What it costs is every geolocation database that still reads the first octets as a country.
