If MS gives an IP address, and if it is available in the static pool configured in the
PDIF, then PDIF allows session to be established using the specified IP address.If
MS gives the IP address of 0.0.0.0 then PDIF assigns an IP address from the
pool.If MS gives an IP address that is not available in any of the static pools
defined on the PDIF, then the PDIF disconnects the session.
