You can edit /etc/network/interfaces to define all the parameters associated 
with a particular port.  For example:

auto eth0
iface eth0 inet static
    pre-up /sbin/modprobe ipv6
    pre-up /sbin/ip6tables-restore  -c < /etc/network/ip6tables.rules
    pre-up /sbin/iptables-restore   -c < /etc/network/iptables.rules
   
    address 69.33.100.126
    netmask 255.255.255.248
    network 69.33.100.120
    broadcast 69.33.100.127
    gateway 69.33.100.121
    
    dns-nameservers 69.33.100.122 173.230.152.5 66.80.130.23
    dns-search jamhome.us, michaelsnet.us
    
    post-up /sbin/ip -6 addr  add 2001:470:e953:cafe::46/64 dev eth0
    post-up /sbin/ip -6 route add default via 2001:470:e953:cafe::42
