CentOS - Jul 2020 - setting kernel IP boot values

Hi I found this information:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-configuring_ip_networking_from_the_kernel_command_line

Specifically:
Set the configuration using the ip option on the kernel command line:
ip<client-IP-number>:[<server-id>]:<gateway-IP-number>:<netmask>:<client-hostname>:<interface>:{dhcp|dhcp6|auto6|on|any|none|off}
dhcp - DHCP configuration
dhpc6 - DHCP IPv6 configuration
auto6 - automatic IPv6 configuration
on, any - any protocol available in the kernel (default)
none, off - no autoconfiguration, static network configuration
For example:
ip=192.168.180.120:192.168.180.100:192.168.180.1:255.255.255.0::enp1s0:off

but I am confused.

I desire to set IP boot values with DHCP and name of machine say jerry.

so I would use ip=::::jerry.domain:eth0:dhcp


Is this correct ?

I tried that on a VM - it still has localhost as the name it did not use
jerry.domain in my example.

I just need DHCP boot and to be able to set the machine name on boot. How
is that done on the kernel boot?

I also just tried systemd.hostname=jerry.domain and that did not work
either.
