alias to show my own configured ip

alias showip="ifconfig eth0 | grep 'inet addr:' | sed 's/.*addr\:\(.*\) Bcast\:.*/\1/'"
parses the output of ifconfig to show only the configured ip address (in this case from interface eth0). the regexp is quick'n'dirty im sure it can be done in a better way. --> this alias does not show your "internet ip" when you're in a nat-environment
Sample Output
$ showip
192.168.0.55

and if we have two (or more) active network interfaces?

ifconfig $if | egrep -o "inet addr:[^ ]*"

Assuming that the default route is via the network interface of interest: /sbin/ifconfig $(netstat -rn | grep "^0.0.0.0" | awk '{print $8}') | awk -F: '/inet addr/ {printf("%s\n",substr($2,1,index($2," "))) }'

there must be a simpler way to do this...
