Configuring Dynamic Domain Name Resolution - HP FlexNetwork MSR2003 Configuration Manual

Follow these guidelines when you configure static domain name resolution:
•
For the public network or a VPN, each host name maps to only one IPv6 address. The most
recent configuration for a host name takes effect.
•
You can configure the following items:
IPv6 DNS entries for the public network and up to 1024 VPNs.
A maximum of 1024 IPv6 DNS entries for the public network or each VPN.
To configure static domain name resolution:
Step
1. Enter system view.
2. Configure a mapping between
a host name and an IPv6
address.

Configuring dynamic domain name resolution

To send DNS queries to a correct server for resolution, you must enable dynamic domain name
resolution and configure DNS servers. A DNS server manually configured takes precedence over the
one dynamically obtained through DHCP, and a DNS server configured earlier takes precedence. A
name query is first sent to the DNS server that has the highest priority. If no reply is received, it is
sent to the DNS server that has the second highest priority, and so on.
In addition, you can configure a DNS suffix that the system automatically adds to the provided
domain name for resolution. A DNS suffix manually configured takes precedence over the one
dynamically obtained through DHCP, and a DNS suffix configured earlier takes precedence. The
DNS resolver first uses the suffix that has the highest priority. If the name resolution fails, the DNS
resolver uses the suffix that has the second highest priority, and so on.
Configuration guidelines
Follow these guidelines when you configure dynamic domain name resolution:
•
You can specify DNS server IPv4 addresses as follows:
Specify DNS server IPv4 addresses for the public network and up to 1024 VPNs.
Specify a maximum of six DNS server IPv4 addresses for the public network or each VPN.
•
You can specify DNS server IPv6 addresses as follows:
Specify DNS server IPv6 addresses for the public network and up to 1024 VPNs.
Specify a maximum of six DNS server IPv6 addresses for the public network or each VPN.
An IPv6 name query is first sent to the IPv6 DNS servers. If no reply is received, it is sent to the
IPv4 DNS servers.
•
You can specify DNS suffixes as follows:
Specify DNS suffixes for the public network and up to 1024 VPNs.
Specify a maximum of 16 DNS suffixes for the public network or each VPN.
