Configuring IP addresses and FQDNs in a non-DNS environment

When DNS is not configured for the cluster, you can add IP addresses and the corresponding FQDN entries to the /etc/hosts file of both the cluster nodes. Adding these entries is required when you configure AutoSupport for a cluster where DNS is not configured.

To add an IP address and FQDN entry to the /etc/hosts file:

Enter the following command:
```
Network> host add ipaddr fqdn
```
ipaddr
Specify an IPv4 or an IPv6 address.
fqdn
Specify the Fully Qualified Domain Name (FQDN) of the IP address. The FQDN can include the following characters: a-z|A-Z|0-9 or a hyphen (-)

To delete an IP address and FQDN entry from the /etc/hosts file:

Enter the following command:
```
Network> host del ipaddr fqdn
```
ipaddr
Specify the IP address that you want to delete.
fqdn
Specify the corresponding FQDN.

To display the entries in the /etc/hosts file:

Enter the following command:
```
Network> host show
```
