Spend some time and come with your script showing your effort towards it.. if we find that you really tried something..but could not solve it.. then we will answer... here we just want to see what you have learned from Forum after 300+ posts.

Hope other members also agree with my words.

I am using sed to change the ip address, but i don't understand the logic how to increment last two numbers, only that part is left.

It will check the last two digits and add the increment one number in it. If it is 23 it will change to 24, and if it is 24 then it will change to 25.
So, if all that you wanted was to have the serial number incremented, why didn't you say that? What the first message in this thread said was that you had some "original text" and "text need to be replaced" with no explanation for the logic behind incrementing one field, doubling another field, subtracting 4 from another field, and subtracting 54 from another field.

If you change the serial number in this file, how do you know that it won't match another serial number that has already been assigned in another file? And according to the comments in you data, these are serial numbers for January 13th in the year xx18???

From what you posted, how did you expect people in this forum (who want to help you) to be able to figure out what you wanted to be done?

Why not tell us how you know what the new IP address should be so both the serial number and the IP address can be changed in one invocation of awk instead of trying to coordinate changes by awk and sed for a single input file?

In the original posting, the 1st line was untagged. The remainder of the post was surrounded by a single set of CODE tags.

I made the only edit to that posting. My edit surrounded the input and output in separate CODE tags leaving the other "descriptive" text untagged. I also added the moderator's comment.
