AS15471 — SNR-

AS15471 announces 78 IPv4 prefixes covering 29,952 addresses and 1 IPv6 prefixes.

About this network

Seventy-eight routes carved out of one range, and every address answers.

What it's used for

• A national broadcast and telecommunications operator. Seventy-eight IPv4 prefixes and one IPv6 /32 announced from Romania, nearly thirty thousand addresses, across twenty-three observed BGP neighbours.

Notable

• Almost every prefix comes from the same large range, sliced into /22 and /23 pieces with gaps between them, which is why one network needs seventy-eight routing table entries.
• Reverse names reverse the octets and label the role: a word for network on the first address of a block, a word for broadcast on the last, the bare octet in between, and an extra label for fixed assignments.
• All eighteen sampled addresses answered, with no exceptions to the scheme.
• Registrant fields run to four entries per block, separating the operations crew, a planning group, and an abuse contact.
• The AS handle ends in a bare hyphen, cut off where a longer string used to continue.

Interesting

• Naming the first and last address of every block publishes the network's internal boundaries. Reading the reverse zone tells an outsider exactly where each subnet starts and stops.
• Seventy-eight routes for thirty thousand addresses is the cost the rest of the internet pays for this network's fragmentation, carried in every routing table worldwide.
• A separate planning contact alongside operations is unusual and suggests a structure large enough to keep address planning as its own job.
