AS12533 — RMNET

AS12533 announces 2 IPv4 prefixes covering 1,024 addresses and 0 IPv6 prefixes.

About this network

Two Italian /23s registered on the same day, one of them carrying a host named for the national electricity company.

What it's used for

• Business internet access. 1,024 addresses in two IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• Both blocks, 82.145.98.0/23 and 82.145.100.0/23, share the netname IT-RMNET-20030610.
• They touch end to end — the first stops at 82.145.99.255 and the second starts at 82.145.100.0 — yet they cannot be announced as one /22.
• One address answers enel.rmnet.it, and another v-portal.myvox.it — a second brand inside the same AS.

Interesting

• Two adjacent blocks that still need two announcements is a good illustration of why prefix length is not the same as size. A /22 has to begin on a multiple of four, and these begin at 98 and 100, so the pair straddles the boundary between 82.145.96.0/22 and 82.145.100.0/22. Contiguous address space does not aggregate unless it is also aligned.
• One netname and one date across both says they were granted together, which makes the misalignment a choice made at the registry rather than an accident of two separate requests.
• Naming a host enel puts a customer's identity into the provider's own zone. ENEL is Italy's electricity utility, and a small regional ISP with a dedicated link to one is labelling the circuit so that whoever answers the phone at two in the morning knows immediately whose it is.
• A second domain, myvox.it, answering alongside is the usual sign that the trading name and the network name have drifted apart. The AS is RMNET; what customers buy may not be.
