The lastconfiguration for a host name takes effect.• You can configure host name-to-IPv6 address mappings for the public network and up to 1024VPNs, and configure a maximum of 1024 host name-to-IPv6 address mappings for the publicnetwork or each VPN.To configure static domain name resolution:Step Command Remarks1.
