The biggest ones probably need /16 or even /12 in some cases.What is the definition of a modest and a large ISP? In the RIPE region even the smallest ISP can get a /29 with no documentation necessary. But likely that is all they will ever get because policy requires that you use that /29 at about 30% efficiency if you do /48 allocations to end users. You would need more than a million users to get a /24. I do not think the RIPE region has an ISP large enough to apply for a /16 or anything near it.
there are 4 organizations that originate something on the order of a /19 1 AS7922 ORG+TRN Originate: 36318243454976 /18.95 Transit: 38476054528 /28.84 COMCAST-7922 - Comcast Cable Communications, Inc.,US 2 AS3320 ORG+TRN Originate: 35219269156864 /19.00 Transit: 569424150528 /24.95 DTAG Deutsche Telekom AG,DE 3 AS5511 ORG+TRN Originate: 35188667187200 /19.00 Transit: 17818772963328 /19.98 OPENTRANSIT Orange S.A.,FR 4 AS17676 ORG+TRN Originate: 18695992639488 /19.91 Transit: 12885032960 /30.42 GIGAINFRA Softbank BB Corp.,JP
Therefore we can conclude that if ARIN manages to use up all the /3 address space currently reserved for allocation, we will still be able to get address space in Europe for the next thousands years :-). It is thought that RIPE will not use up the /12 that IANA allocated to RIPE - ever. Personally I believe the ARIN policy is the sane one. But we need to abide by the rules in the region we live in.
