About this network

Every sampled address answered, including the ones at the top and bottom of each block that normally answer to nobody.

What it's used for

• A regional fibre provider's network. 14,080 addresses across 17 IPv4 prefixes plus one IPv6 prefix, 2604:900::/32, with three observed BGP neighbours. First seen in 2000.

Notable

• Netnames run FLNET-17, FLNET-24, FLNET-35, FLNET-37 and FLNET-41, all registered to FirstLight Networks, LLC, with blocks from the same allocation sharing a number.
• Two /24s carry the netname WMGLLC, registered to Wilmorite Management Group, LLC.
• All eighteen sampled addresses returned a name, every one of the form 98-159-212-0.static.firstlight.net.

Interesting

• The sample always includes each block's first and last address, and here both answered: 176-115-178-0.static.firstlight.net and 176-115-179-255.static.firstlight.net. A reverse zone generated straight from the address arithmetic makes no exception for the network and broadcast addresses, because the generator has no idea they are special.
• The netname suffixes count allocations rather than describing them. Numbers as far apart as seventeen and forty-one on space held by one company are a ledger of separate requests made over many years, each filed as it arrived.
• A property management company's two /24s sitting inside a fibre provider's announcements is a business customer whose address space stayed in its own name while the routing moved.
• Three neighbours and a first sighting in 2000 describe a network that has been in the table since the table was young, and has never needed many ways out.
