AS14702 — INL-ASN2

AS14702 announces 2 IPv4 prefixes covering 131,072 addresses and 1 IPv6 prefixes.

About this network

Two sixteen-bit blocks, no smaller pieces, and the same organisation filed under two different names.

What it's used for

• A national laboratory's network. 131,072 addresses across exactly two IPv4 prefixes, 134.20.0.0/16 and 141.221.0.0/16, plus one IPv6 prefix, 2620:0:2b80::/44.
• Two observed BGP neighbours.

Notable

• Both blocks register to Idaho National Laboratory.
• The netnames are INL on one and IDAHO-NATIONAL-LABORATORY on the other.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Two prefixes for 131,072 addresses is a network that has never had to explain itself to the routing table. Nothing is split out, nothing is announced separately, which means every part of this laboratory reaches the internet the same way.
• One organisation, two netnames, one an abbreviation of the other. The registry has no rule about which form to use, so the answer depends on who filled in the form and when. Any attempt to count organisations by netname will read this as two.
• A research network of this size with nothing answering a reverse lookup keeps its published surface to a minimum. The address space is large; the amount of it that will tell you anything is zero.
• The sample here is six addresses rather than the usual eighteen, because the sampler takes a few per prefix and there are only two prefixes to take them from.
