About this network

Fourteen of fifteen names were generated from the address; the fifteenth is a machine named after its processor speed.

What it's used for

• A regional provider. 1,792 addresses across five IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• Three blocks are netname DLS-CIDR-1 and two are DLS-CIDR-3, all registered to DLS Internet Services, Inc.
• Reverse names take the form 209-242-58-128.rev.dls.net.
• One address answered with 233mhz2.dls.net instead.
• Fifteen addresses were queried and fourteen returned a name.

Interesting

• Naming a server after its clock speed dates the machine to within a couple of years and then keeps saying so forever. The number was a selling point once; it survives as a hostname because renaming a machine means finding everything that refers to it.
• The 2 on the end says there was a first one. Someone bought a pair, named them by the only thing that distinguished them from the previous pair, and moved on.
• The netnames count one and three with no two in between, which is what a registry looks like after a block is returned, transferred, or was never announced from this AS in the first place.
