The DHCP service requires a pool of IP addresses. An IP pool is a sequential range of IP addresses within the network. Virtual machines protected by the edge gateway that do not have an address binding are allocated an IP address from this pool. An IP pool's range cannot intersect one another, thus one IP address can belong to only one IP pool.
