AS13849 — BLOCKINETIC

AS13849 announces 2 IPv4 prefixes covering 512 addresses and 1 IPv6 prefixes.

About this network

Two netnames built by the same rule, except one has a doubled hyphen where the other has a single.

What it's used for

• A hosting network. 512 addresses across two IPv4 prefixes, the IPv6 block 2602:fbb5::/36, and 38 observed BGP neighbours.

Notable

• 23.133.82.0/24 is netname BLOCKINETIC-NET-23-133-82-0-1.
• 173.243.228.0/24 is netname BLOCKINETIC--NET-173-243-228-0-1, with two hyphens after the company name.
• Both are registered to the same company and follow the same construction otherwise.
• 38 upstreams carry 512 addresses.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• The doubled hyphen is the sort of typing slip a template would have prevented and a registry will never correct. Anything matching netnames by pattern treats the two blocks as unrelated, which is the practical cost of building identifiers by hand.
• Thirty-eight adjacencies against two /24s is the highest ratio of paths to addresses in this stretch. Networks reach that number by peering at exchanges rather than buying transit, so the AS exists to collect connections and the address count is almost beside the point.
• The single IPv6 block dwarfs both IPv4 blocks by an amount that has no useful comparison, which is the normal asymmetry between the two families seen at its starkest.
