Each host name can correspond to only one IPv6 address. A newlyconfigured IPv6 address will overwrite the previous one.Follow these steps to configure a static IPv6 DNS entry:To do… Use the command… RemarksEnter system view system-view —Configure a static IPv6 DNSentryipv6 host hostnameipv6-address RequiredConfiguring dynamic DNS resolutionIf you want to use the dynamic domain name function, you can use the following command to enablethe dynamic domain name resolution function. In addition, you should configure a DNS server so that aquery request message can be sent to the correct server for resolution. The system can support at mostsix DNS servers.You can configure a domain name suffix so that you only need to enter some fields of a domain nameand the system automatically adds the preset suffix for address resolution. The system can support atmost 10 domain name suffixes.Follow these steps to configure dynamic DNS resolution:
