This is what I do:
onet=`/sbin/ifconfig dc0 | grep -w inet | awk '{print $2}' | awk -F. \
'{print $1 "." $2 "." $3 ".0"}'`
omask=`grep subnet-mask /var/db/dhclient.leases | tail -1 | sed \
"s/[,;]//g" | awk '{print $3}'`
oip=`grep fixed-address /var/db/dhclient.leases | tail -1 | sed \
"s/[,;]//g" | awk '{print $2}'`
dns1=`grep domain-name-servers /var/db/dhclient.leases | tail -1 | sed \
"s/[,;]/ /g" | awk '{print $3}'`
dns2=`grep domain-name-servers /var/db/dhclient.leases | tail -1 | sed \
"s/[,;]/ /g" | awk '{print $4}'`
dhcp=`grep dhcp-server /var/db/dhclient.leases | tail -1 | sed "s/;//g" |\
awk '{print $3}'`
