For that specific problem, I use the following code snippet at the
top of my .emacs file:

[At home my laptop gets an IP address in the 10.22.33 subnet;
 while at work, I get something else]

(setq at-home-p
      (if (fboundp 'network-interface-info)
          (let* ((info (network-interface-info "eth0"))
                 (ip (and info (car info))))
            (and ip
                 (= (aref ip 0) 10)
                 (= (aref ip 1) 22)
                 (= (aref ip 2) 33)))))

Then I simply add tests 

 (if at-home-p ...home_setup...   ...work_setup...)

around settings (like which SMTP server to use) that differs
at home and at work.
