I've asked someone here what range of ip's should I order for my new internet connection. I'm looking for PI ip's so I can do full bgp peering with two ISP's. I'm based in the UK so RIPE is our assigner.
So far I've been told that to do full bgp peering with two different ISP's I need to order a /24 range as that is the lowest range at which BGP can summarise on the internet. Is that true? What will happen if I get less that that e.g /25 or /27 etc..
