RHEL Terminal Prompt is "unknown"

In my RHEL 7, my terminal prompt changes from localhost to UNKNOWN when I connect to the Internet. Why?

Solution
    • What you see at the prompt at the terminal is a name assigned by your DHCP Server appended by your MAC Address. Try to search for dhclient.conf might be in /etc/dhcp

    Edit the request statement and remove the host-name out of the list. It should be like this

    request subnet-mask, broadcast-address, time-offset, routers,
        domain-name, domain-name-servers, domain-search, host-name,
        netbios-name-servers, netbios-scope, interface-mtu,
        rfc3442-classless-static-routes, ntp-servers
