Configuring Dynamic Domain Name Resolution - HPE FlexNetwork 10500 Series Configuration Manual

•
For the public network or a VPN instance, each host name maps to only one IPv6 address. The
most recent configuration for a host name takes effect.
•
The system allows a maximum of 1024 IPv6 DNS entries for the public network or each VPN
instance. You can configure IPv6 DNS entries for both public network and VPN instances.
To configure static domain name resolution:
Step
1. Enter system view.
2. Configure a host name-to-IPv6
address mapping.

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:
•
The system allows a maximum of six DNS server IPv4 addresses for the public network or each
VPN instance. You can specify DNS server IPv4 addresses for both public network and VPN
instances.
•
The system allows a maximum of six DNS server IPv6 addresses for the public network or each
VPN instance. You can specify DNS server IPv6 addresses for both public network and VPN
instances.
•
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.
•
The system allows a maximum of 16 DNS suffixes for the public network or each VPN instance.
You can specify DNS suffixes for both public network and VPN instances.
