+ CONFIG_BOOTP_DNS2 - If a DHCP client requests the DNS

+ If CONFIG_BOOTP_DNS2 is enabled, the secondary DNS

+ CONFIG_BOOTP_SEND_HOSTNAME - Some DHCP servers are capable
+ to do a dynamic update of a DNS server. To do this, they
+ need the hostname of the DHCP requester.
+ If CONFIG_BOOP_SEND_HOSTNAME is added to the
+ CONFIG_BOOTP_MASK, the content of the "hostname"
+ environment variable is passed as option 12 to
