AS13188 — TRIOLAN

Network type: residential

AS13188 announces 27 IPv4 prefixes covering 410,880 addresses and 27 IPv6 prefixes.

About this network

The registered holder is literally named Content Delivery Network Ltd, and it is a consumer ISP.

What it's used for

• A broadband operator in Ukraine. 410,880 addresses across 27 IPv4 prefixes and 33 IPv6 prefixes, including four full /16s.

Notable

• Every block is registered to CONTENT DELIVERY NETWORK LTD with netnames of the form UA-CDNETWORK-20090820.
• All eighteen sampled addresses returned names such as 0.64.57.37.triolan.net, the four octets in reverse order.
• Netname dates span 2001 to 2012.
• The routing-status lookup failed, so nothing here rests on it.

Interesting

• A company name that reads as a description of a service is a trap for anything classifying networks by string matching. Nothing about this network's shape suggests content distribution; the name is a name, and the netname abbreviation CDNETWORK makes it worse.
• The reverse names reverse the octets, matching the order the DNS tree already uses, so 37.57.64.0 becomes 0.64.57.37. Elsewhere in this range the same idea is done forwards. Both are unambiguous; only one reads like an address.
• Full reverse coverage on every sampled address, including block-base and block-end addresses, confirms these names are generated across the whole space rather than assigned by hand.
• Four /16s under one holder is a large legacy footprint for a regional operator.
