Poll system for IPs

[w1nn3r]

How can i poll the system for IP's configured on the system, i could use ifconfig | grep inet but i was looking for a more clean option. Also would there be a way to only display IPs that dont have a certain port open, like netstat -an | grep :8080 so that it only show's IPs without port 8080 open. Thanks for your help

#1:

/sbin/ifconfig | awk '
{
       if ( (p = match($0,/inet addr:[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+/) ) > 0) {
          printf"Address found at: %s\n", substr($0,(RSTART + 10),(RLENGTH - 10)
)
     }
}'

#2
netstat -an | grep -v ":8080"
