      I replaced the comma’s in a comma-separated list of IP addresses with ‘\n’ in a CRLF (Windows) document

      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

          Hello is there any option to sort ip addresses if they followed by other data in columns

          @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:

                              perhaps quietly, corrupt a user’s file

                              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.
