Get IP section from host command
How do i get only the IP part from a host call.
For example in my script i put
Code:
#!/bin/sh -
#
#       @(#)daily.local       Tim Golding
#

# Back up
server_ip=`host roadhaulage.com`
echo $server_ip

This echos the following

roadhaulage.com has address 86.54.98.194 roadhaulage.com mail is handled by 10 mail2.roadhaulage.com. roadhaulage.com mail is handled by 1 mail.roadhaulage.com.

But i only want the 86.54.98.194 to be returned to $server_ip

Any ideas?

This seems close
Code:
server_ip=`host roadhaulage.com | awk '{printf "%s",$4}'`
echo $server_ip

But it is returning the fourth word in each sentence so im getting

86.54.98.194handledhandled
