AS16652 — RISEUP

Network type: hosting

AS16652 announces 3 IPv4 prefixes covering 768 addresses and 1 IPv6 prefixes.

About this network

Two addresses answer with a name that says they are unallocated.

What it's used for

• A service provider's network. Three IPv4 prefixes and one IPv6 prefix announced from the United States, seven hundred and sixty-eight addresses, through fifteen observed BGP neighbours.

Notable

• Two blocks are the holder's own. One netname is the two-word name; the other appends three letters and a digit that name no place or function a reader can recover.
• The third block belongs to a different company, under a netname beginning with the word legacy, then a brand, then the word block and a counter.
• Eight of nine queried addresses answered, and they are hand-named machines rather than generated ones: a test host, a numbered mail exchanger, a machine for remote virtualisation.
• Two of them answer with the word unallocated on the holder's own domain.
• Two more answer on domains belonging to other projects entirely, one for blogging and one for a separate piece of software.

Interesting

• A reverse name reading unallocated is an intentional placeholder. The operator filled the zone so every address answers something, and chose to state plainly that nothing lives there yet. Most operators leave the gap silent instead.
• Fifteen upstreams for seven hundred addresses is among the highest ratios in this corpus, and says reachability from many directions matters more here than size does.
