AS12736 announces 1 IPv4 prefixes covering 1,024 addresses and 0 IPv6 prefixes.

About this network

The national airports operator, on 1,024 addresses and three upstreams.

What it's used for

• Networking for a national airports authority. 1,024 addresses in a single IPv4 prefix, three observed BGP neighbours, and no IPv6 announced.

Notable

• The whole inventory is 192.115.176.0/22, netname IAA-BLOCK.
• The registrant is the Israel Airports Authority itself, with an abuse role as the only other contact.
• Three sampled addresses were queried and none returned a name.
• 192.115 is legacy space from the early days of the registry.

Interesting

• This is the second airport operator in this stretch of the number range, after a French one holding a single /24. Airports keep their own address space for the same reason hospitals and ports do: the systems that matter have to survive a change of telecoms supplier, and renumbering an operational network is harder than paying for independence.
• Three upstreams for 1,024 addresses is a high ratio of redundancy to size. What is being bought is not capacity but the certainty that no single provider outage takes the airport off the network.
• IAA-BLOCK is a netname with no date, no country prefix and no structure, which places it among the earliest style of registry entry. It was filed when there were few enough blocks that a short name was still unambiguous.
