About this network

A crew-transport contractor's /24, named after the Kansas suburb it is operated from.

What it's used for

• Corporate connectivity. 256 addresses in a single /24 with two observed BGP neighbours and no IPv6 announced.

Notable

• The AS handle is HALLCON-ASN-01 and the block, 67.208.58.0/24, is netname HALLCON-LENEXA-01.
• Both carry an -01 suffix, in a scheme that expects more of each.
• First seen in routing data in April 2007.
• Two neighbours rather than one.

Interesting

• Lenexa is a suburb on the Kansas side of the Kansas City metropolitan area, and putting the town in the netname is site-level bookkeeping: the name says which building the addresses terminate in, which matters the day somebody has to trace a circuit.
• Hallcon moves railway crews. Train operators cannot leave a crew at the end of a shift wherever the train stopped, so a contractor drives them between yards, hotels and terminals around the clock. It is a business made of vehicles, schedules and dispatch systems.
• Two upstreams for a single /24 is a dispatch operation buying redundancy. If the office goes offline the crews still have to be moved, and somebody has to be able to tell them where.
