I'm in a situation where a site has an existing Internet connection that we're using, but we have a larger pipe dropping soon that has a large c block assigned. Notwithstanding, in the interim I have to deal with what we have.
I am not aware of the topology of their current infrasctructure except that they've given us a Cisco switch with 4 ports, each with a separate public ip assigned to each interface. I am, unfortunately, needing a smallish block of IPs for this one interface right now (perhaps 5-10) and I am not exactly sure of the appropriate questions to ask nor what to tell them regarding getting this in position for my SonicWALL router to accept so that it can make the appropriate assignments for devices inside of it's network.
It seems that I may need to grok BGP and ASN's a little better to tell them what I want, but perhaps I'm going too far into implementation in my mind for this issue.
At any rate, I'd certainly appreciate understanding what I need to ask and explain a bit better to get this temporary fix in place.
