AS15312 — -Reserved AS-

AS15312 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

The AS handle reads -Reserved AS-, and it is announcing a route.

What it's used for

• A wholesale goods company's network. A single IPv4 /24 announced from the United States, no IPv6, and one observed BGP neighbour.

Notable

• The registry returns -Reserved AS- where a handle should be, so the number's own record says it has not been assigned, while the routing table shows it carrying traffic.
• The netname names the company's four initials and a counter, and the registrant names the company in full, so the block itself is documented normally.
• This is the fourth number in this range whose handle reads as reserved, which makes it a pattern in the registry rather than a one off.
• Three addresses were queried for reverse DNS and none returned a name.
• Two hundred and fifty-six addresses behind one upstream.

Interesting

• A reserved handle on an active number usually means the assignment was recorded in one system and never propagated to the other. The routing works regardless, because BGP does not consult the registry before accepting a route.
• It does break attribution. Anyone looking up this number gets a placeholder, and only the block's own record names the company.
• The counter on the netname implies an earlier block that is no longer announced, which is the only hint here of a larger past.
