About this network

The reverse names embed this network's own AS number as a label in the hostname.

What it's used for

• The network of an Italian book distribution company. 256 addresses in one IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.

Notable

• The single prefix is 193.27.202.0/24, netname EMMELIBRI-NET.
• All three sampled addresses returned names of the form 64.as13160.messita.net.
• The reverse zone sits under a domain unrelated to the holder.
• One observed BGP neighbour.

Interesting

• as13160 as a hostname label is unusual and quietly sensible. A provider generating reverse names for many customers needs a per-customer label that is guaranteed unique and never has to be invented, and the customer's AS number is exactly that. It also means the reverse DNS identifies the network more reliably than most registry fields do.
• Only the final octet varies, so each address gets a name derived purely from arithmetic. Nothing in the name says what the machine is, which is the trade for having names at all.
• The zone belongs to the upstream, not the distributor. Reverse DNS is delegated by whoever holds the address block, so a small customer's names live in its provider's domain unless someone asks otherwise.
• A single /24 behind one neighbour is a company's own office and systems, connected once.
