\nTo use this utility for a single zone file, run the following command, specifying the appropriate parameters:
\n
\n \/usr\/local\/cpanel\/bin\/swapip $sourceip $targetip $ftpip $domains
\n<\/code>
\nNote: $sourceip, $targetip, $ftpip, and $domains are meant to symbolize the parameters you wish to enter.<\/p>\n\n
\n Example: 127.0.0.0
\n * targetip (string) \u2014 The new IP address.
\n Example: 208.77.188.166
\n * ftpip (string) \u2014 The new FTP server\u2019s IP address.
\n Example: 208.77.188.166
\n * domains (string) \u2014 One or more domains associated with the IP address being changed.
\n Example: example.com\n<\/li>\n<\/ol>\n
\n
\n\/usr\/local\/cpanel\/bin\/swapip 127.0.0.0 208.77.188.166 208.77.188.166 example.com
\n<\/code>
\nwould change the nameserver records for example.com on 127.0.0.0 to point HTTP and FTP requests to 208.77.188.166.<\/p>\n

\n208.77.188.166 example.com
\nroot@example [~]#
\n<\/code>
\nAn unsuccessful swapip attempt should result in an error message, the output of which will resemble the following:
