Mapping DNS Hosts
The switch saves the frequently-queried domain names acquired from the DNS
servers into the local DNS cache. The cache can hold up to 64 static entries, 64
dynamic entries, and one entry for each IP address configured on the switch by
DHCP. Name resolution always begins by checking these static entries, continues
by checking the local DNS cache, and ends by sending requests to the external
DNS server.
The Host Mapping Page enables configure static mappings between a DNS host
name and an IP address.
Several IP addresses are supported per DNS per host name.
To add a domain name and its IP address:
Click IP Configuration > Domain Name System > Host Mapping. The Host
Mapping Page opens.
This page displays the following fields:
•
Host Name—User-defined domain name, up to 158 characters.
•
IP Address—The host name IP address.
Click Add. The Add Host Mapping Page opens.
Enter the parameters.
•
IP Version—Select Version 6 for IPv6 or Version 4 for IPv4.
•
IPv6 Address Type—Select the IPv6 address type (if IPv6 is used). The
options are:
-
Link Local—The IPv6 address uniquely identifies hosts on a single
network link. A link local address has a prefix of FE80, is not routable, and
can be used for communication only on the local network. Only one link
local address is supported. If a link local address exists on the interface,
this entry replaces the address in the configuration.
-
Global—The IPv6 address is a global Unicast IPV6 type that is visible and
reachable from other networks.
