How to go about Using a "Validate an IP script" in conjunction with Logfile?

Hi, so I have been trying to write a shell script to go through a log file and through that, generate another file with all the Valid IP addresses it finds. So there's the complication that there could be incomplete or invalid data which would disqualify it from making my "Valid IPs" file I need to generate.

So I already have working code/script which can check if a chunk of stuff with no spaces in it is one Valid IP or not. That seems to work fine.

Problem is, I don't know specifically what else do I need to do and/or code and how to use my function in conjunction with a log file and how to make things work together.

Though I have ways of reducing the data set of useless lines , (i.e. by calling grep), I'm not completely sure if that's best to do and how to best pass in the reduced data set where I can still traverse it and/or how to traverse it so that my function/script can work on Validating if each potential chunk is a real IP or not.
I am willing to edit this function to traverse several lines of potential chunks, but don't know how to traverse nor get each chunk within the lines.
Or what should I do?

For example, let's say log file has following format:

maryjane from 10.23.17.11
johnston4 from 20..70.81
mail server exception, port 3209
controller from 321.24.70.18
brady from 110.113.270.
carriemoon from 111.123.199.291
error type 209.134 handled
barkleyjohnson from 0.43.205.34
bishopqueen from 2.100.999.8
billyj from 71.253.82.114
firewall and security handler invoked Mar 15 05:24:33
freewill from 28.49.130.
marklouis from .111.250.230

Anyways, I don't know how to go about all this.
Code and suggestions would help and be appreciated

Thanks in advance.

NAME
script -- make typescript of terminal session SYNOPSIS
script [-a] [-f] [-q] [-t] [file] DESCRIPTION
Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1). If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript. Options: -a Append the output to file or typescript, retaining the prior contents. -f Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and another can super- vise real-time what is being done using `cat foo'. -q Be quiet. -t Output timeing data to standard error. This data contains two fields, separated by a space. The first field indicates how much time elapsed since the previous output. The second field indicates how many characters were output this time. This information can be used to replay typescripts with realistic typing and output delays. The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not set) for the C-shell, csh(1)). Certain interactive commands, such as vi(1), create garbage in the typescript file. Script works best with commands that do not manipulate the screen, the results are meant to emulate a hardcopy terminal. ENVIRONMENT
The following environment variable is utilized by script: SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most shells set this variable automatically). SEE ALSO
csh(1) (for the history mechanism), replay(1). HISTORY
The script command appeared in 3.0BSD. BUGS
Script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects. Linux July 30, 2000 Linux
