Static configuration of network interfaces is generally achieved by
editing /etc/network/interfaces ("man interfaces). A likely stanza to do
what you want might be:

   auto eth0
   iface eth0 inet static

Depending on circumstances you may be able to leave out the broadcast
and/or gateway lines.

For IPv6 it looks like this:

   auto eth0
   iface eth0 inet6 static
      address 2001:db8:0:100::3
      netmask 64

There is no broadcast address in IPv6, and the gateway will generally be
delivered via router advertisements.
