Hello All, It is known that current EDKII doesn't support RFC3021, We could see the following behavior which is PXE boot fails whereas Cent OS can get IP address from the same BIOS. [Configuration Used] DHCP server setting under Ubuntu: 1. /etc/dhcp/dhcpd.conf # RFC3021-Using 31-bit perfixes

Hi Fu Siyuan, Thanks for your conformation. We would like to use /31s to save IPv4 addresses. When it's a point-to-point link (server to router), the extra network address and broadcast address is wasted. RFC 3021 solves the problem by using a broadcast address of 255.255.255.255 on such subne
