在父部分：

DNS Parent sent Glue The parent
nameserver g.gtld-servers.net is not
sending out GLUE for every nameservers
listed,meaning he is sending out your
nameservers host names without sending
the A records of those nameservers.
It’s ok but you have to know that this
will require an extra A lookup that
can delay a little the connections to
your site. This happens a lot if you
have nameservers on different TLD
(domain.com for example with
nameserver ns.domain.org.)

在NS部分：

Glue for NS records INFO: GLUE was not
sent when I asked your nameservers for
your NS records.This is ok but you
should know that in this case an extra
A record lookup is required in order
to get the IPs of your NS records. The
nameservers without glue are:
109.230.225.96
84.201.40.52 You can fix this for example by adding A records to your
nameservers for the zones listed
above.

我完全理解粘合记录的主要目的是解决循环依赖.

经典用例：

我的域名是example.com,我想拥有名称服务器ns1.example.com.这将无法工作,因为我无法知道ns1.example.com的ip,如果我不提取example.com,为了做到这一点,我需要从ns1.example.com获取它.为了解决这个死锁问题,我在ns1.example.com中添加了一条胶水记录,其中包含了名称服务器的ip地址,因此可以解决这个问题.

因此,如果名称服务器与我想查找的域名不同,则不会出现此问题.但是,要从名称服务器获取区域信息,我需要知道他们的IP地址吗？并且为了知道我需要获取区域名称服务器来自各自的名称服务器,对吧？ (或者说我的ISP需要在后台执行此操作)所以额外的查找需要时间吗？

如果我现在有胶水记录,我立即知道IP地址而无需查找 – 所以这应该加快我的域名的解决速度,不是吗？

但是,我的DNS区域提供程序(tecserver.at)回复说

this would make no sense because “we
are not running ns1.ourdomain.com an
ns1.ourdomain.com as authorative NS for
ourdomain.com.

This would be the only sense for glue
records.

Tecserver has a glue record because
the NS for tecserver.at are
ns1.tecserver.at and ns2.tecserver.at.
Therefore a glue record is needed for
resolution.
