AS14043 — SCANSOURCE
AS14043 announces 2 IPv4 prefixes covering 2,048 addresses and 0 IPv6 prefixes.
About this network
Every address in a block answers with the name of the block's first address.
What it's used for
- A technology distributor's network. 2,048 addresses across three IPv4 prefixes, with six observed BGP neighbours and no IPv6 announced.
Notable
- Six of nine sampled addresses answered, and the answers resolve to only three distinct names.
- Each name is the block's own starting address written with dashes, so 204.10.4.128 and 204.10.4.255 both return 204-10-4-0.scansourceinc.com.
- Two blocks share the netname SCANSO-BLOCK1 and the third carries SCANSO-BLOCK2, with a network operations role contact on the first two.
Interesting
- A single record covering a whole block, naming it after its first address, is a wildcard. It gives every address a name for the benefit of tools that insist on one, while telling you only which subnet you have reached. As a compromise between publishing everything and publishing nothing it is a reasonable one, and it is rare enough to be worth recognising.
- The side effect is that reverse lookups cannot distinguish machines, which quietly breaks the logging and access rules that assume a name identifies a host.
- Six upstreams for a network of this size is a lot. A distributor's ordering systems talk to thousands of resellers and manufacturers all day, and the connectivity is sized for that rather than for the address count.
- The netnames number the blocks in the order they arrived rather than by address.
