About this network

The one address that answers is a gateway, named after the two numbers that locate it.

What it's used for

• A transport and logistics company's network. 2,048 addresses in a single IPv4 prefix, with three observed BGP neighbours and no IPv6 announced.

Notable

• 170.203.248.0/21 carries the netname LANDSTAR, matching the company, with the company as registrant.
• One of three sampled addresses answered, with gw253-254.landstar.com.
• The AS first appeared in routing on 2001-01-18.

Interesting

• The published name is a router, marked as such by two letters and located by the last two parts of its address. Gateways are the addresses most often given names in an otherwise silent block, because engineers need to talk about them and because monitoring systems read better with names than numbers.
• It also means the naming is by hand rather than generated. A template would have covered every address in the block; this covers the equipment somebody cared about.
• A logistics business runs on connections to customers, carriers and load boards rather than on public services, so a single block behind three upstreams with almost nothing named is exactly the expected shape.
• The block is intact and announced as one route, which is worth noting in a range where splitting is the norm.
