About this network

A regional provider with an IPv6 allocation sized for a network many times larger than the one it runs.

What it's used for

• A rural access provider. 5,120 addresses across three IPv4 prefixes, one IPv6 prefix, and four observed BGP neighbours.

Notable

• Two blocks are netname YKC-TEXAS, registered to Y K Communications, LTD.
• The third block's registry lookup failed and says nothing either way.
• The IPv6 prefix is 2604:bdc0::/32.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• The netname names a state rather than the company's role or a block number, which is how a provider labels space when the thing worth recording is where the subscribers are.
• Four upstreams for five thousand addresses is generous. A provider serving areas with few alternatives buys its redundancy at the top of the network, because there is no second route into a town that has one road.
• IPv6 is handed out by organisation rather than by need, so a small provider receives a prefix that would serve a national carrier. It costs nothing to hold and removes address scarcity from the operator's problems permanently.
