      Works great. Tiny addition: make sure you have the correct EOL. I replaced the comma’s in a comma-separated list of IP addresses with ‘\n’ in a CRLF (Windows) document. Sorting as described above produced unpredictable (to me) results.

        For the benefit of any future readers, what you should have done is a regular-expression replacement with \r\n for a Windows document.

        Sorting as described above produced unpredictable (to me) results.

        What does this mean? You also said “Works great”–so which is it?

          Hello is there any option to sort ip addresses if they followed by other data in columns? This method is not working. For example:

          IP MAC
          192.168.1.140 0023-ac20-3918
          192.168.1.49 08ea-2931-ca12
          192.168.1.145 08ea-2903-bc32
          192.168.1.133 98f1-12ca-2456
          192.168.1.73 9440-21ab-2512
          192.168.1.134 eceb-565a-2953
          192.168.1.132 d067-bc22-3174

            @guy038’s regex above assumed the whole line was an IP.

            But with a slight tweak – allowing a space or tab to come after the final digits, not just a dot or newline – makes it match any of your examples. So his first FIND WHAT becomes (?:^|(?<=\.))\d(\d)?(?=\.|\h|$)

            His first replacement (with spaces) works… but it’s harder to undo later when you have other spaces in the rest of your line. So I change his first REPLACE WITH to 0(?1:0)$0 so that it inserts one or two zeroes instead of one or two spaces

            So
            FIND = (?:^|(?<=\.))\d(\d)?(?=\.|\h|$)
            REPLACE = 0(?1:0)$0
            SEARCH MODE = regular expression

            That search/replace will give you

            192.168.001.140 0023-ac20-3918
            192.168.001.049 08ea-2931-ca12
            192.168.001.145 08ea-2903-bc32
            192.168.001.133 98f1-12ca-2456
            192.168.001.073 9440-21ab-2512
            192.168.001.134 eceb-565a-2953
            192.168.001.132 d067-bc22-3174
            

            Now you can sort lexicographically ascending as he recommended.

            Then you need to change the second search/replace. Instead of searching for spaces and removing them, what we want to do is search for leading zeroes and remove them.

            FIND = \b0+(?=\d+?(?=\.|\h))
            REPLACE = leave empty
            SEARCH MODE = regular expression

            This got me to

            192.168.1.49 08ea-2931-ca12
            192.168.1.73 9440-21ab-2512
            192.168.1.132 d067-bc22-3174
            192.168.1.133 98f1-12ca-2456
            192.168.1.134 eceb-565a-2953
            192.168.1.140 0023-ac20-3918

              In addition to Peter Jones’ solution, you can also do this in a single operation with the Columns++ plugin.

              Select the lines you want to sort.

              Select Sort… from the Columns++ menu.

              Columns++ Sort for IP addresses.png

              Select:
              What to sort: Whole lines
              Sort type: Ascending and Numericundefined
              Sort key: Regular expression

              Check: Specify keys using capture groups.

              Enter:
              Find what: (\d+)\.(\d+)\.(\d+)\.(\d+)
              Keys: 1,2,3,4

              Click OK.

              When asked to “Convert to a rectangular selection enclosing the selected lines?” click OK.

                  @PeterJones hello the problem with this command is that it also could change MAC address deletes “00” from it.

                      I was afraid you were going to realize that exception.

                      (?:^|\.)\K0+(?=\d+?(?=\.|\h))

                      This changes the requirement to whatever goes before the leading zero digits must be either start of line or a period. But because of the \K, you have to use Replace All (it will not work with a single Replace)

                      When I tried my old one on

                      192.168.001.020 d067-bc22-0004
                      

                      it wrongly became

                      192.168.1.20 d067-bc22-4
                      

                      but when I tried my modified expression, it correctly became

                      192.168.1.20 d067-bc22-0004
                      

                      But if @Coises’s plugin solution works for you, I’d go that way, because it doesn’t involve as much complication, and ensures that it’s only dealing with the digits inside an IP address.

                        The Python solution hasn’t been discussed here and as that thread is very old I’ll post here.
                        … I need 1 reputation point to post links, so here it is - remove the spaces!
                        https:// community.notepad-plus-plus .org/topic/11105/feature-request-sort-by-ip-address-cidr-notation

                        Those scripts didn’t work for me so I wrote my own. This handles both IP & CIDR interchangeably.

                        import re
                        
                        addresses = editor.getText().split('\n') # Contents to string array
                         
                        non_blank_addresses = [] # Filter out blank lines
                        for addr in addresses:   #  and clean the input data using regular expressions.
                          cleaned_addr = re.sub(r'\s', '', addr)  # Remove whitespace
                          if cleaned_addr:       # Check if not empty
                            non_blank_addresses.append(cleaned_addr)
                        
                        # Sort all addresses (CIDRs and individual IPs)
                        sorted_addresses = sorted(non_blank_addresses, key=lambda addr: (
                          tuple(map(int, re.split(r'[/.]', addr)))[:-1],  # Extract IP components
                          int(re.split(r'[/.]', addr)[-1]) if '/' in addr else 32  # Extract and convert prefix length
                        ))
                        
                        editor.beginUndoAction()
                        editor.setText('\n'.join(sorted_addresses))
                        editor.endUndoAction()

                          This script will, perhaps quietly, corrupt a user’s file, because it changes line endings from Windows’ type (CRLF) to Linux type (LF). :-(

                            AlanKilborn is correct.

                            My practice in any file when I’m dumping lines is to do something like this:

                            # Near the top of the script (with other global constants)
                            EOLS = ('\r\n', '\r', '\n')
                            # code
                            #...
                            # whenever I want to choose newline, do this:
                                eol = EOLS[editor.getEOLMode()]

                              My version of that is eol = ['\r\n', '\n', '\r'][editor.getEOLMode()]… the same, but all in one place.

                                I spoke before of:

                                and then I presented some code which does just that. :-(


                                Instead of:

                                eol = ['\r\n', '\n', '\r'][editor.getEOLMode()]

                                in my posting immediately above, it should have been:

                                eol = ['\r\n', '\r', '\n'][editor.getEOLMode()]

                                (note that the '\r' and the '\n' were swapped in the erroneous code)

                                My apologies for the error.
