This is the default setting for the cPanel traceroute client.
To increase the number of hops, you must use a command-line tool. For example, using the cPanel Terminal, you can set the maximum number of hops to 255 with the following command:
traceroute -m 255 xx.xx.xxx.xxx
Note: Replace xx.xx.xxx.xxx with your server’s IP.
See the General Information Panel in cPanel for the IP.
