AS14673 announces 3 IPv4 prefixes covering 1,536 addresses and 0 IPv6 prefixes.

About this network

One netname says which town the fibre serves; the other two say almost nothing.

What it's used for

• A fibre provider's network in Canada. 1,536 addresses across three IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• 172.81.0.0/22 carries the netname UXBRIDGE-FIBER, naming both the place and the medium.
• 170.39.33.0/24 and 170.39.34.0/24 both carry the netname FB-EG.
• All three blocks are registered directly to the company.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• The two smaller blocks sit next to each other but cannot be joined into one announcement, because a pair only merges when the lower half starts on an even boundary. Ending up with adjacent blocks that still need two routing entries is one of the small frustrations of receiving address space in the order the registry has it free rather than in the order that would be convenient.
• Naming a block after the town it serves is how a regional provider keeps track of build-outs, and it means the registry doubles as a rough map of where the network reaches. The four-letter netname on the other two gives up nothing by comparison.
• Nothing published in reverse DNS and two upstreams is the ordinary shape for a provider whose customers are homes and small businesses rather than servers.
• Address space from two very different ranges means the older allocation and a much later purchase now sit under one operator.
