IPv6 DNS服务器怎么写？

IPv6 DNS服务器的配置方法如下：

1. 操作系统设置

Linux (systemd-resolved)

临时设置
sudo resolvectl dns <interface> 2001:4860:4860::8888 2001:4860:4860::8844
sudo resolvectl domain <interface> example.com
永久设置
sudo nano /etc/systemd/resolved.conf

[Resolve]
DNS=2001:4860:4860::8888 2001:4860:4860::8844
Domains=example.com
DNSStubListener=yes

Linux (NetworkManager)

使用nmcli
sudo nmcli con mod <connection-name> ipv6.dns "2001:4860:4860::8888,2001:4860:4860::8844"
sudo nmcli con mod <connection-name> ipv6.dns-search "example.com"
sudo nmcli con up <connection-name>
编辑配置文件
sudo nano /etc/NetworkManager/system-connections/<connection-name>.nmconnection

[ipv6]
method=auto
dns=2001:4860:4860::8888;2001:4860:4860::8844;
dns-search=example.com;

Windows

PowerShell
Set-DnsClientServerAddress -InterfaceAlias "Ethernet" -ServerAddresses ("2001:4860:4860::8888","2001:4860:4860::8844")
图形界面
1. 控制面板 → 网络和共享中心 → 更改适配器设置
2. 右键网卡 → 属性 → IPv6 → 属性
3. 使用以下DNS服务器地址

macOS

设置IPv6 DNS
sudo networksetup -setdnsservers Wi-Fi 2001:4860:4860::8888 2001:4860:4860::8844
sudo networksetup -setsearchdomains Wi-Fi example.com
查看配置
networksetup -getdnsservers Wi-Fi

2. 常用IPv6 DNS服务器地址

公共DNS服务器

Google DNS:
2001:4860:4860::8888
2001:4860:4860::8844
Cloudflare DNS:
2606:4700:4700::1111
2606:4700:4700::1001
Quad9:
2620:fe::fe
2620:fe::9
OpenDNS:
2620:0:ccc::2
2620:0:ccd::2
阿里DNS:
2400:3200::1
2400:3200:baba::1
百度DNS:
2400:da00::6666

3. 路由器配置

OpenWRT/LEDE

编辑网络配置
vi /etc/config/network

config interface 'lan'
    option proto 'static'
    option ip6assign '60'
    list dns '2001:4860:4860::8888'
    list dns '2001:4860:4860::8844'
    option dns_search 'example.com'

DD-WRT

网页管理界面：
Setup → Basic Setup → Network Address Server Settings (DHCP)
启用Use DNSMasq for DNS
在Additional DNSMasq Options中添加：
dhcp-option=option6:dns-server,[2001:4860:4860::8888],[2001:4860:4860::8844]

4. DNS服务器软件配置

BIND9

named.conf.options
options {
    listen-on-v6 { any; };
    forwarders {
        2001:4860:4860::8888;
        2001:4860:4860::8844;
    };
    allow-query { any; };
};
zone文件添加AAAA记录
$ORIGIN example.com.
@    IN    AAAA    2001:db8::1
www  IN    AAAA    2001:db8::2

dnsmasq

dnsmasq.conf
listen-address=::1,127.0.0.1
server=2001:4860:4860::8888
server=2001:4860:4860::8844
dhcp-range=::100,::1ff,constructor:eth0

Windows Server DNS

1、服务器管理器 → 添加角色 → DNS服务器
2、DNS管理器 → 右键服务器 → 属性
3、转发器 → 添加IPv6地址
4、区域文件添加AAAA记录

5. 验证配置

测试DNS解析
dig AAAA google.com @2001:4860:4860::8888
nslookup -type=AAAA google.com 2001:4860:4860::8888
查看当前DNS配置
ipconfig /all          # Windows
resolvectl status      # Linux (systemd)
cat /etc/resolv.conf   # Linux (传统)
scutil --dns           # macOS
测试连接
ping6 google.com
traceroute6 google.com

6. 注意事项

1、双栈支持：建议同时配置IPv4和IPv6 DNS

2、路由器通告：确保路由器发送正确的RDNSS选项

3、防火墙：开放UDP/TCP端口53（IPv6）

4、优先顺序：系统会根据RFC 6724决定使用IPv4还是IPv6

7. 高级配置示例

systemd-networkd

/etc/systemd/network/eth0.network
[Match]
Name=eth0
[Network]
DHCP=yes
IPv6AcceptRA=yes
DNS=2001:4860:4860::8888
DNS=2001:4860:4860::8844
Domains=example.com

动态DNS更新

使用nsupdate添加AAAA记录
nsupdate -k keyfile <<EOF
server dns.example.com
zone example.com
update add host.example.com 3600 AAAA 2001:db8::1
send
EOF

根据你的具体需求和环境选择合适的配置方法。
