How can a DHCP client assume that a remembered address can be still used?It can't assume.
If the lease is still valid, it can use it and contact the server via unicast, if there is no valid lease, it must not use the IP anymore because it could be assigned to some other node.I think it SHOULDN'T use would be the proper nomenclature.
IIRC IP unicast src addr can only be used if the lease is still valid and the client wants to extend the lease.Maybe.
Of course asking the DHCP for additional information after the IP has been assigned is another situation where unicast can be used.Yep.
Does anybody know other situations?I assume that a release would also be unicast.
