You don't need eval, 1 parse is enough.
Code:
#!/usr/bin/ksh
#simple script to grep for the IP of the host in any file
echo -n "Enter the IP address you want to find:"
read IP
log=/tmp/ipfind.out.$IP
echo "greping all files for $IP"
echo "This will take a considerable amount of time to complete..."
echo "Scripts logs to /tmp/ipfind.out.$IP"
# IP include ., which is special char for regexp, so you need change . -> \.
IP="${IP//./\\.}" 
# find regular files and grep IP, take time, output only filenames which include $IP
find / -type f -exec grep -l "$IP" {} \;  > $log  2>/dev/null
echo "Script complete. please check $log"

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
