Windows is not allowed to create hostname greater than 15 characters to my knowledge. Is there any plan to increase the hostname length greater than 15 in new Windows release? Can you please share the details.

Thanks,

    Hi @James J ,

    The limit is simply from the NETBIOS protocol, which has a limit of 16 bytes for the computername. So, if Windows will use the NETBIOS protocol, then the limitation will remain valid.
