A DNS server for the "senet" domain which provides name resolution for communication runs on the MU. The DNS server is configured in such a manner that it performs name resolutions for "senet" itself and forwards other name resolutions to external DNS servers which must be configured manually.
The static IPv6 address of the local MU is the first name server in the DNS configuration of the MU. Two further external DNS servers and the external domain search list can be configured.
The IPv6 addresses of the two possible MUs are preconfigured on an SU x86 or HNC. No further configuration is required.
DNS queries are thus directed to the MU via the network segment MCNPR. The MU then either resolves the address itself for the "senet" domain or forwards the request to the customer's external DNS servers.
Name resolutions can also be used for the other network segments MONPR and DANPR. For this purpose the relevant network segments must be configured on the MU in the SE Manager, and IPv6 autoconfiguration must be enabled (see section "Managing the IP configuration").
