About this network

Its reverse names mark the network and broadcast addresses with a single letter, n or b.

What it's used for

• A provider's network. 8,192 addresses across 12 IPv4 prefixes, with a single observed BGP neighbour and no IPv6 announced.

Notable

• Eleven blocks carry the netname GAMMANET-BLK1, registered to Gamma Networking Inc.
• 66.152.85.0/24 carries GAMMANET-66-152-85-0-85-255, registered to MARKET ENGINES, a netname that writes out the first and last address of the block.
• Thirteen of eighteen sampled addresses returned a name. Ordinary addresses answer host-66-152-77-254.gammanetworking.com, while the first and last of each block answer subnet-66-152-74-0-n.gammanetworking.com and subnet-66-152-75-0-b.gammanetworking.com.
• One address answers under a different domain entirely, wajam.com.

Interesting

• Most generated reverse zones treat every address alike. This one distinguishes three kinds: a host, a subnet's base address marked n, and its broadcast address marked b. Both special names refer to the subnet rather than the address queried, so a lookup on the last address of a block answers with the first.
• Twelve announcements out of one contiguous range, all under one netname, is a network splitting space it received as a whole. The single neighbour means none of that split is about routing choice.
• A netname spelling out both ends of a block, on the one prefix registered to somebody else, is a customer assignment recorded more carefully than the operator's own space.
