      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
      192.168.1.145 08ea-2903-bc32

        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

        192.168.1.132 d067-bc22-3174

        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.
