Hi, So I'm curious - what is the proposed method to move a single IP across zones (presuming these zones span regions). As Chiradeep mentioned earlier, /24 is the largest block that will be advertised, so it would necessitate moving (or advertising in two locations, and back hauling back to one) an entire class C to accomplish this (or some black magic like LISP).
My other question revolves around the actual usefulness of EIP across regions, and whether or not the problem can be solved simply with DNS changes / global load balancing.
