To test the number itself, this might do it:
set IPAdd to "
233.240.123.1" -- my sample. Try with invalid numbers too.
set {TID, text item delimiters} to {text item delimiters, "."}
set parts to (text items of IPAdd)
set text item delimiters to TID
set CP to count of parts
if CP > 4 or CP < 4 then
display dialog "An IP Address must have four elements separated by periods"
else
repeat with k from 1 to 4
set aNum to item k of parts as number
if aNum > 253 or aNum < 1 then
display dialog ("In your entry: " & parts as string) & ", " & (item k of parts) & " must be a number between 1 and 254"
exit repeat
end if
end repeat
display dialog ("Your entry: " & parts as string) & " is a valid address"
end if

IPs are of the form

So you want to
1. Split on "."

This would be a start

set oldDelimiters to AppleScript's text item delimiters
set AppleScript's text item delimiters to "."
set x to text items of a
set AppleScript's text item delimiters to oldDelimiters
--return count x
if (count x) ‚ 4 then
display dialog "I need 4 numbers separated by periods (not " & (count x)
& ").
Your string was: " & a
