查询本地lan主机名时取消绑定dns服务器响应

我在Windows上,我已经配置了 Unbound 用作Android Emulator的DNS(自 -dns-server 似乎不起作用*)。DNS服务器取自 ipconfig /all .

我可以从未绑定的日志中看出,它正在查询我试图从emulator浏览的任何网页,但本地LAN名称无法解析,而Internet名称则无法解析。

从日志中,我看不到任何返回:

info: resolving <local-lan-server-name>. AAAA IN
info: response for <local-lan-server-name>. AAAA IN

而对于Yahoo主机名:

以下是配置:

# Unbound configuration file on windows.
# See example.conf for more settings and syntax
server:
    # verbosity level 0-4 of logging
    verbosity: 3

    interface: 0.0.0.0
    infra-cache-min-rtt: 250
    access-control: 0.0.0.0/0 allow_snoop

    do-ip4: yes
    do-ip6: no
    do-udp: yes
    do-tcp: yes

    logfile: "C:\unbound.log"
    log-time-ascii: yes
    log-queries: yes
    log-replies: yes

    unblock-lan-zones: yes
    insecure-lan-zones: yes

    auto-trust-anchor-file: "C:\Program Files\Unbound\root.key"

forward-zone:
    name: "."
    forward-addr: 10.241.6.11
    forward-addr: 10.241.11.48
    forward-addr: 10.241.11.49

*:事实上,当我给模拟器提供我在Unbound中配置的相同DNS ip地址时,我得到了相同的行为,当Internet名称(如www.yahoo.com)工作时,本地LAN名称不会被解析。

这是什么 nslookup 关于这个主机名:

C:\> nslookup <local-lan-server-name>
Server:  <dns-server-name>
Address:  10.241.11.48

Nome:    <local-lan-server-name>
Address:  10.241.11.27

所以我猜DNS服务器的配置是正确的。
