While doing some further testing, I came up with a few questions. If you had the following input file:
what, if any, valid IP addresses would you like your script to report? I'm guessing that none should be found here, but one of the scripts you posted early in this thread will come up with something like the following:
I'm looking at a different way to evaluate possible IP addresses, but I need to know what you want to be required to appear before and after a valid IP address. Am I correct in assuming that a valid IP address should appear at the start of a line or be preceded by a white-space character, be followed by a white-space character or appear at the end of a line, and contain four 1 to 3 digit numbers separated by single occurrences of a period where the values of the numbers are 0 <= number <= 255?
Note that if my assumption is correct, an IP address surrounded by alphabetic or punctuation characters (in addition to slashes) should also be rejected. If my assumption is correct, should an exception be made allowing commas (or comma followed by space) to separate IP addresses?
Are we having fun yet?

isalpha
ISALPHA(3) BSD Library Functions Manual ISALPHA(3)NAME
isalpha -- alphabetic character test
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
isalpha(int c);
DESCRIPTION
The isalpha() function tests for any character for which isupper(3) or islower(3) is true. The value of the argument must be representable
as an unsigned char or the value of EOF.
In the ASCII character set, this includes the following characters (preceded by their numeric values, in octal):
101 ``A'' 102 ``B'' 103 ``C'' 104 ``D'' 105 ``E''
106 ``F'' 107 ``G'' 110 ``H'' 111 ``I'' 112 ``J''
113 ``K'' 114 ``L'' 115 ``M'' 116 ``N'' 117 ``O''
120 ``P'' 121 ``Q'' 122 ``R'' 123 ``S'' 124 ``T''
125 ``U'' 126 ``V'' 127 ``W'' 130 ``X'' 131 ``Y''
132 ``Z'' 141 ``a'' 142 ``b'' 143 ``c'' 144 ``d''
145 ``e'' 146 ``f'' 147 ``g'' 150 ``h'' 151 ``i''
152 ``j'' 153 ``k'' 154 ``l'' 155 ``m'' 156 ``n''
157 ``o'' 160 ``p'' 161 ``q'' 162 ``r'' 163 ``s''
164 ``t'' 165 ``u'' 166 ``v'' 167 ``w'' 170 ``x''
171 ``y'' 172 ``z''
RETURN VALUES
The isalpha() function returns zero if the character tests false and returns non-zero if the character tests true.
COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered
obsolete and may not be supported in future releases. The iswalpha() function should be used instead.
SEE ALSO ctype(3), isalnum_l(3), islower(3), isupper(3), iswalpha(3), ascii(7)STANDARDS
The isalpha() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
