[AusNOG] What is more important? - ipv4 vs. routing table size

[Rick Jones]

Hi Skeeve,

Customers can be multi-homed without a direct APNIC allocation by going to the right ISP.  If an ISP is carrier neutral, there is nothing stopping them from multi-homing themselves across multiple carriers and then passing this on via diverse paths to their customers.  They would have /22 or larger allocation but could pass this on to the client as /24s.  This is our business model (although only for people who are in our data centre) and I dare say that we are not unique.



Best Regards,

Subject: [AusNOG] What is more important? - ipv4 vs. routing table size

Hey all,

I'd like to stimulate some discussion regarding IPv4 conservation vs. The size of the routing table.

I'd like to hear what people think is more important - and why - which it is more important - or a miz?


IPv4 conservation - possibly allocating smaller default allocations - or making it easier (/24, /23)

vs.

The size or the routing table.  If by a more conservative allocation above was done, and the world table jumped to 400, 500 thousands or more routes - what implications would this have on routers and so on.

APNIC's minimum is a /22 (was a /19 in 2000) (4 * /24's)
ARIN is a /20 to ISPs (16 * /24's)
RIPE is a /21 (8 * /24's)
LANIC is a /21 (I think)
AFRINIC is a /22 (4 * /24's)

There are smaller hosting companies out there (here in ANZ at least) that want to be on, hosting, multi-homed, but only need a /24 or /23, but they're given the minimum allocation on a /22 - whether they need it or not.

Thoughts?
