About this network

Fifty-two thousand addresses, sixty-four announced prefixes, and one observed neighbour.

What it's used for

• A colocation provider's network in the United States. 52,480 addresses across thirty-one IPv4 prefixes, thirty-three IPv6 prefixes, and one observed BGP neighbour.

Notable

• Netnames run ZC38-BLOCK2, ZC38-BLOCK3, ZC38-BLOCK4, ZC38-BLOCK8 through ZC38-BLOCK12.
• The same block number covers several separate announcements: ZC38-BLOCK3 holds both a /20 and a /22, ZC38-BLOCK11 and ZC38-BLOCK12 each hold two.
• Sampled names are cust-108-60-207-255.corexchange.com, with some carrying a site code: cust-67-211-43-254.dllstx01.corexchange.com.
• One address answers under a different domain entirely, zcd.bissinc.us.
• One prefix's registry lookup failed, so nothing is known about its registration here.

Interesting

• A single neighbour for a network this size means everything reaches the internet through one parent company. The colocation business was acquired by its upstream, and the routing shows the result: a large, well-populated network with exactly one door.
• The block numbers are the acquisition ledger. Each is one allocation, later cut into several routes, so counting distinct numbers gives the number of times the company obtained space and counting prefixes gives the number of times it needed to steer traffic separately.
• Site codes appear in some reverse names and not others, which is two generations of zone tooling running side by side.
