REGEX Tool for IP Ranges (allow, filter, etc...)

[VaultBoss 310]

I was trying to write some REGEX to filter out the LAN IPs and I found that MightyG has a dedicated tool for that.

 

Thought I'd share, maybe you guys will need such a thing sometimes...

Enjoy!

For example, for filtering out the IP Range:

 

10.0.0.0 ----- 10.255.255.255

 

....this tool gives a long and complex (but thoroughly made) string such as:

 

^10\.([0-9]|[1-9][0-9]|1([0-9][0-9])|2([0-4][0-9]|5[0-5]))\.([0-9]|[1-9][0-9]|1([0-9][0-9])|2([0-4][0-9]|5[0-5]))\.([0-9]|[1-9][0-9]|1([0-9][0-9])|2([0-4][0-9]|5[0-5]))$

 

This would be useful if you are not sure how the IP would be generated, especially if human interaction is implied, because it selects the IPs properly, within the accepted ranges available for each class (0-254)

 

However, if you don't care too much about that (say the IP is correctly formated, being resulted from an automated procedure), you could simplify it a lil' bit as shown on the website I mentioned under the first link, like this string below:

 

^10\.\d+\.\d+\.\d+$

+1 to you.

Here is an example code to test the above REGEX in Ubot:

 

ui text box("Check IP for Private/Public Range: ", #var_TEST_IP)
set(#var_IP_Type_Public, $nothing, "Global")
ui button("Query") {
set(#var_IP_Query_Result, $Public_IP_Range(#var_TEST_IP), "Global")
}
ui stat monitor("Result - IP is Public?", #var_IP_Type_Public)
divider
divider
define $Public_IP_Range(#var_TEST_IP) {
set(#var_TEST_IP, $trim(#var_TEST_IP), "Local")
set(#var_TMP_IP, $replace regular expression(#var_TEST_IP, "(^10\\.\\d+\\.\\d+\\.\\d+$)", $nothing), "Local")
if($comparison($text length(#var_TMP_IP), "<", $text length(#var_TEST_IP))) {
 then {
	 set(#var_IP_Type_Public, "False", "Global")
 }
 else {
	 set(#var_TMP_IP, $replace regular expression(#var_TEST_IP, "(^172\\.(1[6-9]|2[0-9]|3[01])\\.\\d+\\.\\d+$)", $nothing), "Local")
	 if($comparison($text length(#var_TMP_IP), "<", $text length(#var_TEST_IP))) {
		 then {
			 set(#var_IP_Type_Public, "False", "Global")
		 }
		 else {
			 set(#var_TMP_IP, $replace regular expression(#var_TEST_IP, "(^192\\.168\\.\\d+\\.\\d+$)", $nothing), "Local")
			 if($comparison($text length(#var_TMP_IP), "<", $text length(#var_TEST_IP))) {
				 then {
					 set(#var_IP_Type_Public, "False", "Global")
				 }
				 else {
					 set(#var_TMP_IP, $replace regular expression(#var_TEST_IP, "(^169\\.254\\.\\d+\\.\\d+$)", $nothing), "Local")
					 if($comparison($text length(#var_TMP_IP), "<", $text length(#var_TEST_IP))) {
						 then {
							 set(#var_IP_Type_Public, "False", "Global")
						 }
						 else {
							 set(#var_TMP_IP, $replace regular expression(#var_TEST_IP, "(^127\\.0\\.0\\.1$)", $nothing), "Local")
							 if($comparison($text length(#var_TMP_IP), "<", $text length(#var_TEST_IP))) {
								 then {
									 set(#var_IP_Type_Public, "False", "Global")
								 }
								 else {
									 set(#var_IP_Type_Public, "True", "Global")
								 }
							 }
						 }
					 }
				 }
			 }
		 }
	 }
 }
}
return(#var_IP_Type_Public)
}

 

I just included the other ranges too.

Thanks for the share man just in time for a bot I am working on.
