Local Loop

I’ve finally gotten around to writing the scripts to update my South African Autonomous Systems list. The table will now be updated using routes from the IS route server on a regular basis. I’ve made the following changes:

• As per Joe’s request, it is now sorted first by the equivalent number of class C networks (/24 prefixes) advertised, and then by the real number of networks. Unfortunately it also counts sub-prefixes, so for example, UCT’s overlapping /16, /24 and two /17s are counted as 513 /24s instead of 256. I hope to fix this soon. Fixed.
• As per Colin’s request, there is a script that renders the table as machine-processable CSV, here: http://www.localloop.co.za/za_asn.php.
