The Hosts Table enables you to edit the /etc/hosts file through the WebUI or REST interface. Each line in the Hosts file contains one IP address (IPv4 or IPv6) and at least one FQDN/Host name/Domain name.
When you create a FQDN/Hostname entry in the Host Table, you have the option to enter an IP address to resolve the FQDN/Host name, or allow the SBC to dynamically resolve the FQDN/Host name. The Dynamic Refresh option allows dynamic resolution of the FQDN/Hostname, as well as provides auto-updates in case of dynamic IP changes.

Usage Examples
The Hosts Table allows applications on the SBC 1000/2000, such as SIP Signaling Groups, AD, RADIUS, etc. to resolve FQDNs when a DNS server is not reachable. We recommend that only a few, very critical, host-IP pairs be stored on the
.
Another use-case is in a pre-deployment scenario in which an administrator would like to divert traffic by mapping the same FQDN to a different IP address. For example, a
can communicate with a Lync server under test before it is added to the production network, using the same FQDN, but with a different IP address.
