AS13700 — -Reserved AS-

AS13700 announces 7 IPv4 prefixes covering 3,072 addresses and 0 IPv6 prefixes.

About this network

Netnames encode each block's first two octets, and one of them gets its own address wrong.

What it's used for

• A network operator carrying space registered to a carrier. 3,072 addresses across seven IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• The AS handle reads -Reserved AS- even though the holder record names a company.
• Six blocks are registered to a carrier, each netname being an abbreviation plus the block's first two octets.
• 198.173.162.0/23 is netname NTTA-198-170, naming a range three ahead of the one it covers.
• Two blocks in 168.143 share one netname, so that field describes the parent rather than the piece.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A netname built from the address is self-checking by design, which is what makes the mismatch visible. Every other block in the set agrees with itself, and this one does not, so the error is in the field rather than in the announcement.
• A placeholder handle sitting on a named, actively announced AS is the routing registry contradicting itself. The number was marked reserved and then used, and nobody went back.
• The operator's own name appears nowhere in any netname. Everything in the registry names the carrier the space was bought from.
