2 If the DNS properties are set, and you want to change the DHCP seings, you must specify the virtual
network adapter to use when overriding the system DNS.
You can override the existing DHCP seing by using the following commands.
esxcli <conn_options> network ip interface ipv4 set --type dhcp/none/static
esxcli <conn_options> network ip interface ipv6 set --enable-dhcpv6=true/false
Setting the DNS Configuration with vicfg-dns
The vicfg-dns command lists and species the DNS conguration of your ESXi host. You can call the
command without command-specic options to list the existing DNS conguration.
You can also use esxcli network ip dns for DNS management.
I If you try to change the host or domain name or the DNS server on hosts that use DHCP, an
error results.
In network environments where a DHCP server and a DNS server are available, ESXi hosts are
automatically assigned DNS names.
In network environments where automatic DNS is not available or not desirable, you can congure static
DNS information, including a host name, primary name server, secondary name server, and DNS suxes.
Set Up a DNS Server with vicfg-dns
You can use vicfg-dns to set up a DNS server.
The following example illustrates seing up a DNS server. Specify one of the options listed in “Connection
Options for vCLI Host Management Commands,” on page 19 in place of <conn_options>.
Procedure
1 Run vicfg-dns without command-specic options to display DNS properties for the specied server.
vicfg-dns <conn_options>
If DNS is not set up for the target server, the command returns an error.
2
To change the seings, use vicfg-dns with --dns, --domain, or --hostname.
n
Specify the DNS server by using the --dns option and a comma-separated list of hosts, in order of
preference.
vicfg-dns <conn_options --dns <dns1,dns2>
n
Congure the DNS host name for the server specied by --server or --vihost.
vicfg-dns <conn_options> -n dns_host_name
n
Congure the DNS domain name for the server specied by --server or --vihost.
vicfg-dns <conn_options> -d mydomain.biz
3
To turn on DHCP, use the --dhcp option.
vicfg-dns <conn_options> --dhcp yes
Modify DNS Setup for a Preconfigured Server with vicfg-dns
You can use vicfg-dns to modify the setup of a precongured DNS server.
Specify one of the options listed in “Connection Options for vCLI Host Management Commands,” on
page 19 in place of <conn_options>.
