AS15396 — ICM-COM ICM

AS15396 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

The reverse names say plainly that these addresses are core routers.

What it's used for

• A university computing centre's network. A single IPv4 /24 announced from Poland, no IPv6, through two observed BGP neighbours.

Notable

• Every sampled address answered, each with the AS handle, then the full address in dashes, then two labels reading as router and core, under the centre's academic domain.
• The netname is the country code, the centre's three letter abbreviation, and the allocation date.
• The registrant names the university with a word missing from its usual form, and a network department alongside it.
• Three addresses were queried for reverse DNS and three returned a name.
• Two hundred and fifty-six addresses, all of them apparently named.

Interesting

• Naming a device by its role in public DNS is a habit from academic networking, where operators documented their infrastructure for each other. It makes troubleshooting a traceroute far easier.
• It also tells anybody looking exactly which addresses carry the routers rather than the servers, which is a targeting hint given away for free.
• University supercomputing centres often hold address space out of proportion to their size. This one does not, which suggests the research traffic leaves by a different number.
