About this network

The one hostname that answered carries the address backwards, a node identifier, and the AS number itself.

What it's used for

• A privacy network operator. 2,048 addresses in a single IPv4 prefix, one IPv6 prefix, and six observed BGP neighbours.

Notable

• The block is 192.200.152.0/21, netname STL-PHX-SFO, registered to Strong Technology, LLC.
• The AS handle is NETPROTECT-PHX.
• The address that answered gave back 0.154.200.192.client.dyn.strong-in142.as13926.net.
• The IPv6 prefix is 2606:b300:8000::/40.

Interesting

• That hostname is four facts stacked in one string: the address written in reverse, a label marking it as a customer-facing dynamic address, a numbered node, and a domain that is the AS number spelled out. Anyone reading a log line learns which network, which node and which address without a single lookup.
• Naming a domain after your own AS number is a small piece of honesty. The number is public, it never changes while the network exists, and it survives every rebrand the marketing domain will not.
• The netname lists three city codes for one block and the handle repeats one of them. Space used in several cities at once is the normal shape for this kind of service, where the point of an address is where it appears to be rather than where the hardware sits.
