AS14497 announces 5 IPv4 prefixes covering 3,840 addresses and 0 IPv6 prefixes.

About this network

Five separate blocks, all filed under one netname numbered one.

What it's used for

• A hosting provider's network. 3,840 addresses across five IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• Every block carries the identical netname BITREFINERY-1, registered to the company with a contact filed simply as Refinery.
• Eight of fifteen sampled addresses answered, all in the form 208-72-156-190.static.bitrefinery.net.
• The AS first appeared in routing on 2007-07-31.

Interesting

• A netname ending in one, reused on five blocks, is a company that decided its identifier names the company rather than the allocation. It is more consistent than most operators manage and it makes the number on the end meaningless, which is the trade.
• Every published name marks its address as static. That word is doing real work: mail servers refuse connections from addresses that look residential, and a hosting company whose customers cannot send mail has a support problem. The label is aimed at other people's spam filters.
• The addresses that answered are spread across all five blocks, so the reverse zone is generated for the whole estate rather than maintained per block.
• Five blocks between a /22 and a /24, none adjacent, is a provider that has bought space on the transfer market rather than been granted it.
