About this network

Nine routes that could be two, and one netname for all of them.

What it's used for

• A rural telephone company's network. Nine IPv4 prefixes announced from the United States, no IPv6, and two observed BGP neighbours.

Notable

• The nine announcements fall into two families. Five of them tile one unbroken range of sixteen consecutive blocks; the other four tile a range of eight.
• Each family is aligned, so a single announcement could carry each one, and nine entries in every routing table on the internet could be two.
• All nine blocks share the same netname, the company name and the word network, so the registry does not distinguish them either.
• Eighteen addresses were queried for reverse DNS and none returned a name.
• Six thousand addresses in total, behind two upstreams.

Interesting

• This is the sharpest example of unaggregated announcement in this range. Nothing about the routing suggests the pieces are treated differently: same registrant, same netname, same upstreams.
• It usually happens because each piece was turned up separately as the network grew, and nobody went back to combine them once the range was complete.
• The cost is small for any one network and large in aggregate. Tables carry hundreds of thousands of routes, and a meaningful share of them are runs like this one that nobody ever tidied.
