AS13727 announces 7 IPv4 prefixes covering 3,072 addresses and 1 IPv6 prefixes.

About this network

Seventeen upstreams for 3,072 addresses, with four of them named in the netnames of the space they sold.

What it's used for

• A Canadian business internet and managed services provider. 3,072 addresses across seven IPv4 prefixes, the IPv6 block 2606:7080::/32, and seventeen observed BGP neighbours.

Notable

• Four netnames each carry a different upstream's name alongside the operator's: MNSI-NEXTD-BLK1, NEXTD-CGNT-NET-1, ND-LUMEN-1 and BELL-NEXTD-BLK1.
• Registrants on one block append both an abuse contact and a network operations centre.
• Some addresses answer as ptr-216-8-178-254.ptr.nextdimensioninc.com, with the abbreviation for reverse records appearing twice in one name.
• 8.42.8.64 answers as its own address in normal order, prepended to that same zone.
• Customer machines answer under a customer label, as nemak-mi.net.customer.nextdimensioninc.com and mpl-jda-mo.customer.nextdimensioninc.com, with short site codes.
• 216.8.177.255 answers as a hostname naming a security appliance brand on a customer's own domain.

Interesting

• Seventeen neighbours against three thousand addresses is a provider whose product is connectivity choice rather than capacity. Four named upstreams in the registry and thirteen more in the routing data say the same thing twice.
• Customer names and site codes in reverse DNS map which businesses sit on which addresses, which is convenient for the help desk and equally convenient for anyone else.
• Naming the appliance brand on a customer's edge tells a reader what is filtering that connection before they send anything to it.
