bipinajith,
This worked great,
could you please explain a bit this portion , I am unable to unerstand how you got the 3 octet only outof 4 + ":" , with the
Code:
sub(/\.[0-9]+:.*/,x,$4);

Thanks,

Ok got it , that means the 4rth octet and remaining part of $4 substitured with x , that means with nothing value assigned to x, so $4 keeps upto 3rd octet only. Good one. Thanks.
