AS13446 — AS-NETZERO

AS13446 announces 21 IPv4 prefixes covering 27,648 addresses and 0 IPv6 prefixes.

About this network

Three internet service brands in one record: the handle names one, the netnames name another, and the registrant names the company that owns both.

What it's used for

• A consumer internet provider's network. 27,648 addresses across twenty-eight IPv4 prefixes, six observed BGP neighbours, and no IPv6 announced.

Notable

• The AS handle is AS-NETZERO.
• Twelve blocks are netname JUNO-BLK or JUNO-BLK2, a different brand.
• Registrants list a third name, the holding company, alongside its abuse department.
• Eighteen addresses were queried for reverse DNS and none returned a name.
• One prefix's registry lookup failed, so nothing is known about its registration here.

Interesting

• Two of the largest free dial-up services of their era merged into one holding company, and the merger is legible only in the registry. The autonomous system kept one brand's name, the address blocks kept the other's, and neither was renamed because renaming does nothing for the packets.
• Twenty-eight prefixes for 27,648 addresses means an average block smaller than a /21. Dial-up providers accumulated address space in the sizes their modem banks needed, city by city, and the fragments outlast the modems.
• Announcing no IPv6 at all in a network this old is the honest signal that the customer base it was built for is not growing.
