If you're allowed to modify the .login/.profile whatever files...  you
can try something like:

MYIP=`last | `whoami` | head -1 | awk ' { print $3 }'`

Except that last uses the domain name, when available, and will
truncate it...  There may be a command line option to make it not
truncate.  'w' may also be used for the same effect.
