我向 ISP(CableOne)提交了创建 PTR 记录的请求。
160.2.202.58 mail.huntleylaw.com
我查询了 30 多个公共 DNS 服务器,但只能在两个服务器上找到 PTR 记录...
ns1.cableone.net (24.116.0.206)
ns2.cableone.net (24.119.5.34)
这已经远远超过了他们建议的 DNS“传播”最长 72 小时的时间范围
我的问题:什么原因导致 PTR 记录即使过了 5 天也只能在两个公共名称服务器上查询?
答案1
如果这是您请求的地址,则 DNS 设置存在常见问题。
2.160.in-addr.arpa
这列出了需要的DNS 服务器
$ host -vra 2.160.in-addr.arpa
...
;; AUTHORITY SECTION:
2.160.in-addr.arpa. 86355 IN NS ekns03.kodak.com.
2.160.in-addr.arpa. 86355 IN NS ekns01.kodak.com.
2.160.in-addr.arpa. 86355 IN NS ns.kodak.com.
2.160.in-addr.arpa. 86355 IN NS ekns02.kodak.com.
所有服务器都拒绝回答58.202.2.160.in-addr.arpa
。
Host 2.160.in-addr.arpa not found: 5(REFUSED)
cableone DNS 服务器会回答此查询,因为它们认为自己对此查询具有权威性。但是从根开始的查询将转到 kodak DNS 服务器,而它们不会回答。
您应该让您的 ISP 修复此问题,这个问题不仅影响您,还影响更多地址。
