AS13110 — INEA-AS

AS13110 announces 21 IPv4 prefixes covering 171,520 addresses and 2 IPv6 prefixes.

About this network

Each block gets its own letter, which is how truncated reverse names stay unique.

What it's used for

• A Polish cable and internet provider. 171,520 addresses across 21 IPv4 prefixes, two IPv6 prefixes, and 139 observed BGP neighbours.

Notable

• Eighteen of 18 sampled addresses returned names, all of the form c32-0.icpnet.pl: a single letter, then the last two octets.
• The letter changes with the block: c and d on one range, e on another, f on a third.
• Netnames are all PL-INEASP, dated from 20000321 through 20121227.
• The domain answering matches neither the holder nor the netname.

Interesting

• Dropping the first two octets from a generated name makes it short, and it makes it ambiguous: several blocks would produce the same label. The letter is the fix. One character per block restores uniqueness at a fraction of the length, and it works because the operator controls how many blocks there are. Another provider in this range truncated its names the same way without adding the letter, and does have the collisions.
• A perfect answer rate across 18 addresses means the zone is generated for the whole allocation, not filled in by hand.
• Twenty-one prefixes, thirteen years of netname dates, and one naming scheme applied consistently across all of them. That combination is unusual: most holders in this range change convention every few blocks.
