Network type: hosting

AS13767 announces 172 IPv4 prefixes covering 191,488 addresses and 39 IPv6 prefixes.

About this network

Six acquired companies still hold the registry records, and one netname separates its fields with underscores.

What it's used for

• A data centre and colocation operator. 224,000 addresses across 262 IPv4 prefixes, 66 IPv6 prefixes, and 102 observed BGP neighbours.

Notable

• The twelve sampled blocks are registered to six different companies, none of them the AS holder.
• 155.137.32.0/19 is netname NCS-155320, using underscores where every other netname uses hyphens.
• Its registrant carries a trading-as clause naming a second business.
• The IPv6 announcements under 2605:1980 climb by doubling from a /47 to a /42, leaving one piece the size of the smallest of them unaccounted for in the middle.
• 67.22.139.254 answers as unknown.dal.cologlobal.com, the first label saying nothing.
• The AS handle names one metro while the registrants name several others.

Interesting

• A hostname whose first label is the word unknown is a placeholder that was generated rather than chosen. The site code beside it is real, so the name identifies where the address is without identifying what it is.
• Underscores are legal in a registry name field and unusual in one, which makes that object stand out from every sibling. It came from a different company's conventions and was never normalised.
• Six registrants under one AS is the acquisition history of a colocation business written into the address records, with each purchase leaving its own naming scheme behind.
