I also found another way with split:

Code:
awk '{split($4,x,"\.");print $2,x[1]"."x[2]"."x[3]}' file

Bipinajith,

How the regular expression can be formed if there is no ":" after the 4rth octet:
Below example:

file:
Code:
HOST= cmiHOST06    10.26.107.73 /data120 /nbu/cmiHOST06/athpx07/aa1
HOST= cmiHOST05    10.26.12.76 /data120 /nbu/cmiHOST05/athpx07/cc1
HOST= cmiHOST05    10.26.1.75 /data120 /nbu/cmiHOST05/athpx07/dd1
