The lease duration of the addresses on subnet 1::1:0:0:0/96 is 172800seconds (two days), the valid time is 345600 seconds (four days), the domain name is aabbcc.com,and the DNS server address is 1::1:0:0:2/96. The lease duration of the addresses on subnet1::2:0:0:0/96 is 432000 seconds (five days), the valid time is 864000 seconds (ten days), the domainname is aabbcc.com, and the DNS server address is 1::2:0:0:2/96.Figure 61 Network diagramProcedure1.
