Step 8: DNS configuration - DNS address
The Cisco VCS must have at least one domain name server address defined if it is using FQDNs
(Fully Qualified Domain Names) instead of IP addresses when specifying external addresses (for
example for LDAP and NTP servers, neighbor zones and alternates), or when using features such as
URI dialing or ENUM dialing.
1. Go to the DNS page (System configuration > DNS).

1. Go to the DNS page (System configuration > DNS).
2. Enter a valid DNS server IP address (IPv4 if the Cisco VCS is using IPv4, IPv6 if the Cisco VCS is
using IPv6) in the Address 1 field.
3. Click
Save.
Note: Addresses 2-5 can be used for alternate DNS server addresses (for resilience purposes), or
alternatively for DNS server addresses which serve different types of lookup data (for example,
ENUM lookups).
