How to resolve a linux host name to a valid IP Address

/Etc/sysconfig/network
The file is the host name on the network.
/Etc/hosts
The file is the domain name or name corresponding to the IP address.

Does the linux host name automatically change to an IP address? Without any settings, how can I avoid changes?

I used to encounter this situation. Later I found that the host name was set for the NIC. When I restarted, I read the NIC configuration again. View the eth0 or eht1 configuration, which should be written in. /Etc/sysconfig/network-stript/eth0 or eth1

In addition, if your IP address is automatically allocated by DHCP, the name may also be automatically allocated by DHCP.
