Solaris 8 question

Our IP addressing scheme has changed, so have the static IPs for all of our servers. I need to update this information on my Solaris 8 server, to include changing IP and adding the new DNS server address. I’m an experienced NT administrator, and this is my first crack at UNIX. I’ve searched the online docs and man pages, with no help. How tough can it be to change IP and DNS server address? Help! Thanks…..
