      Great post and detailed explanation.

      The following is a solution to a scenario when migrating DHCP reserved MAC addresses. When exporting via command line on server, the subsection regarding reserved IP is not sorted. In efforts to clean-up this list prior to migration, sorting is a great solution.

      Exporting DHCP data from Windows Server via command line as explained here:
      https://support.microsoft.com/en-us/help/325473/how-to-move-a-dhcp-database-from-a-computer-that-is-running-windows-nt

      Export:

      netsh dhcp server dump > C:\dhcp.txt
      

      Import:

      netsh exec c:\dhcp.txt
      

      Within the section “Add ReservedIp to the Scope” each line is dumped like (MacAddress is actual):

      Dhcp Server \\domain.name.local Scope 192.168.10.0 Add reservedip 192.168.10.125 MacAddress "DeviceName" "DeviceName" "BOTH"
      

      Leveraging details from a similar post (below) I was able to adapt a version for my specific needs:
      https://notepad-plus-plus.org/community/topic/11105/feature-request-sort-by-ip-address-cidr-notation

      Enter (?:^|(?<=\.))\d(\d)?(?=\.|$|\s), in the Find what: zone
      Enter \x23(?1:\x23)$0, in the Replace with: zone

      Note: The addition of the pipe, forward-slash, s (match trailing space)
      (I chose ASCII hex 23 (dec 35) number sign as a temporary char place holder not shown in the DHCP server naming. Experiment to see which char works for your needs.)
      http://www.ascii.cl/htmlcodes.htm

      The end result is proper spacing (padded with “hashes”).

      Then sort via “Sort Lines Lexicographically Ascending”
      https://superuser.com/questions/762279/sorting-lines-in-notepad-without-the-textfx-plugin#762281

      Now “unpad” the IP address for later import:
      SEARCH \x23
      REPLACE Leave EMPTY

      Hope this helps.

            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

                  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

                    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.
