i don't think its that cut/dried. it would be really interesting to know how many folks do -ZERO- aggregation, either on their own or proxy-aggregation - today, and how that number might change in the future. i'll posit that today it is nigh impossible to run aggregate-free. ... that ISPs aggregate so they can claim "default-free". i'll also note that there is zero functional difference btwn a /32 in either address family - as far as the FIB/RIB construction is concerned. i may also make the claim that it is going to be harder to stand behind the APNIC shield for defining ones prefix acceptance policy. ISPs are going to have to have the gonads to state which prefixes they prefer and which will get aggregated... regardless of APNIC (or RIR) delegation policy. Tell me why I am wrong. --bill On Fri, Aug 07, 2009 at 01:28:42AM +1000, Skeeve Stevens wrote:
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?
