在一台运行Windows系统的计算上，可以用来来查看IPv6配置信息的常用命令如下所示。
Netsh interface ipv6 show interface。Netsh interface ipv6 show address。Netsh interface ipv6 show route。Netsh interface ipv6 show neighbors。Netsh interface ipv6 show destinationcache。2.9.1 Netsh interface ipv6 show interface该命令可以显示出IPv6的接口列表，下面是输出信息的示例：
Idx Met MTU State Name --- --- ----- ----------- ------------------- 1 50 4294967295 enabled Loopback Pseudo-Interface 1 9 50 1280 enabled Local Area Connection* 6 6 20 1500 enabled Local Area Connection 10 50 1280 enabled Local Area Connection* 7 7 10 1500 disabled Local Area Connection 2在默认情况下，接口名中含有星号（*）的是隧道接口。
2.9.2 Netsh interface ipv6 show address该命令可以显示出各接口的IPv6地址列表，下面是输出信息的示例：
Interface 1: Loopback Pseudo-Interface 1 Addr Type DAD State Valid Life Pref. Life Address --------- ----------- ---------- ---------- ------------------------ Other Preferred infinite infinite ::1 Interface 9: Local Area Connection* 6 Addr Type DAD State Valid Life Pref. Life Address --------- ----------- ---------- ---------- ------------------------ Other Deprecated infinite infinite fe80::5efe:1.0.0.127%9 Interface 6: Local Area Connection Addr Type DAD State Valid Life Pref. Life Address --------- ----------- ---------- ---------- ------------------------ Public Preferred 29d23h59m59s 6d23h59m59s 2001:db8:21da:7:1f3e:9e51:2178:b9ob Temporary Preferred 5d19h59m25s 5d19h59m25s 2001:db8:21da:7:a299:85ae:21da:59cc Other Preferred infinite infinite fe80::713e:a426:d167:37ab%6 Interface 10: Local Area Connection* 7 Addr Type DAD State Valid Life Pref. Life Address --------- ----------- ---------- ---------- ------------------------ Other Deprecated infinite infinite fe80::5efe:1.0.0.1272.9.3 Netsh interface ipv6 show route该命令可以显示出IPv6地址路由表中的路由条目列表，下面是输出信息的示例：
Publish Type Met Prefix Idx Gateway/Interface Name ------- -------- --- ------------------------ --- ----------------------- No Manual 256 ::/0 8 fe80::3cec:bf16:505:eae6 No Manual 256 ::1/128 1 Loopback Pseudo-Interface 1 No Manual 8 2001:db8::/64 8 Local Area Connection No Manual 256 2001:db8::4074:2dce:b313:7c65/128 8 Local Area Connection No Manual 256 2001:db8::b500:734b:fe5b:3945/128 8 Local Area Connection No Manual 1000 2002::/16 11 Local Area Connection* 7 No Manual 256 fe80::/64 10 Local Area Connection* 9 No Manual 256 fe80::/64 8 Local Area Connection No Manual 256 fe80::100:7f:fffe/128 10 Local Area Connection* 9 No Manual 256 fe80::5efe:10.0.0.3/128 17 Local Area Connection* 6 No Manual 256 fe80::b500:734b:fe5b:3945/128 8 Local Area Connection No Manual 256 ff00::/8 1 Loopback Pseudo-Interface 1 No Manual 256 ff00::/8 10 Local Area Connection* 9 No Manual 256 ff00::/8 8 Local Area Connection2.9.4 Netsh interface ipv6 show neighbors该命令可以显示出接口缓存的内容，该缓存中会保存最新解析出来的下一跳地址的链路层地址（MAC地址），显示信息按照接口来分类，下面是输出信息的示例：
Interface 1: Loopback Pseudo-Interface 1 Internet Address Physical Address Type -------------------------------------------- ----------------- ----------- ff02::16 Permanent ff02::1:3 Permanent Interface 8: Local Area Connection Internet Address Physical Address Type -------------------------------------------- ----------------- ----------- 2001:db8::3cec:bf16:505:eae6 00-13-72-2b-34-07 Stale (Router) 2001:db8::4074:2dce:b313:7c65 00-00-00-00-00-00 Unreachable 2001:db8::6c4b:bf6d:201a:ccbf 00-00-00-00-00-00 Unreachable fe80::3cec:bf16:505:eae6 00-13-72-2b-34-07 Stale (Router) ff02::16 33-33-00-00-00-16 Permanent Interface 10: Local Area Connection* 9 Internet Address Physical Address Type -------------------------------------------- ----------------- ----------- fe80::b500:734b:fe5b:3945 255.255.255.255:65535 Unreachable ff02::16 255.255.255.255:65535 Permanent2.9.5 Netsh interface ipv6 show destinationcache这个命令会显示目的缓存的内容，该缓存中会保存目的地址的下一条地址，显示信息按照接口来分类，下面是输出信息的示例。
Interface 8: Local Area Connection PMTU Destination Address Next Hop Address ---- --------------------------------------------- ------------------------- 1500 2001:db8::3cec:bf16:505:eae6 2001:db8::3cec:bf16:505:eae6
