About this network

A city utility selling broadband, with reverse names under a marketing domain.

What it's used for

• A municipal utility's broadband network. Three IPv4 prefixes announced from the United States, no IPv6, and one observed BGP neighbour.

Notable

• The three routes tile one aligned range of sixteen consecutive blocks, so a single announcement could carry all of them.
• All three share one netname, the utility's four letter abbreviation with an abbreviation for network block and a zero padded counter.
• The two answering addresses give the last two octets, then a label combining the word net with the utility's initials, then a marketing domain that names neither the city nor the utility.
• Routing history for this number begins in 2007.
• Nine addresses were queried for reverse DNS and two returned a name.

Interesting

• Municipal utilities that already own poles and conduit are well placed to sell broadband, and this is what that looks like from outside: a city department with four thousand addresses and a consumer brand in its DNS.
• Splitting the range into three routes gains nothing here, since all three leave by the same single upstream. It is fragmentation without a purpose.
• One upstream for a city's broadband service is the exposure worth noting. If that provider fails, the town is offline, and no amount of routing inside the network changes that.
