Quick question from a routing noob:
I've just acquired 210.48.96.88/30. The two IP addresses in the block are intended for a couple of vmware instances. We're not using anything nice like a Cisco router, just a Linksys stand-in for now. It has some basic static routing capabilities.
I had a short conversation with Iconz support but I'm not feeling very confident about the result. I've been instructed (or rather I said "this is what we came up with" and I got a vague "yes") to add the following entry to the routing table (where 202.37.231.84 is the existing IP that we're using as an external address):
Destination: 210.48.96.88 Subnet: 255.255.255.252 Gateway: 202.37.231.84 Interface: Local
Really, ICONZ are the only ones that can answer this, however, if the network in question were a point to point link then what you describe (allocating a /30, or even two disparate random ips) would work due to it essentially being interface routed, but a broadcast network (which most hosts seem to expect when plugged in via ethernet - even simulated) really needs a gateway on the same network or strangeness [tm] tends to happen, I would have assumed that if you already had a /30 from ICONZ for your existing infrastructure that they would just widen this to a /29 for you as it doesn't make for any more or less address space wastage and allows you to do what you want easily. -- Steve.
