Description

获取本地域名服务器地址的方法、装置和权威域名服务器 技术领域
本发明涉及通信技术领域,尤其涉及一种获取本地域名服务器地址的方法、装置和权威域名服务器。
背景技术
网络中的客户端在通过域名访问网络服务前,需要通过域名系统查询域名对应的网络服务器的IP地址,该域名系统包括多级域名服务器(Domain Name Server,DNS服务器)。其中,各级本地域名服务器在接收到本地网络中的客户端发送的域名解析请求后,依次递归查询上级域名服务器,最终通过权威域名服务器把域名解析为IP地址返回给客户端。在CDN(Content Delivery Network,内容分发网络)或ADN(应用交付网络,Application Delivery Network)等一些网络系统中,全局负载均衡系统返回给客户端的IP地址是CDN或ADN网络中离客户端最近CDN或ADN节点的IP地址,以提高网络服务效率。
基于这个原因,ADN或者CDN的全局负载均衡系统需要一个方法获取客户端的位置,一般这是通过一个本地域名服务器IP地址库来实现的,这个地址库存有全球各地本地域名服务器IP地址和对应的地理位置。但是由于全球网络在不断变化中,这个地址库不能百分之百准确。当客户被调度到错误的ADN或者CDN接入节点时,需要一个手段来获取客户端的本地DNS服务器。
但是,现有的通信协议,客户端只能查询与其直接通信的本地域名服务器的IP地址,例如,与该客户端同一小区内的本地域名服务器,该本地域名服务器的IP地址通常是内网IP地址。而更上一级的本地域名服务器的IP 地址客户端无法获取,而具有公网IP地址的本地域名服务器,权威域名服务器可以收到这个服务器的请求,但是无法和相应的客户端对应起来。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
为了使本领域技术人员能够更容易理解本发明实施例提供的技术方案, 下面对涉及到的相关技术进行简单介绍。
图1提供了一种网络系统的架构示意图,如图1所示,包括网络客户端11、与网络客户端11直接通信的第一级本地域名服务器12、与权威域名服务器14直接通信的第二级本地域名服务器13、以及为网络客户端11提供网络服务的CDN/ADN服务器15。
值得说明的是,上述第一级本地域名服务器12通常是指网络客户端11所处小区内的小区DNS服务器,第二级本地域名服务器13可以是运营商在本区域布置的区域DNS服务器,权威域名服务器是指最终将域名解析为IP地址的DNS服务器。
另外,现有技术中,网络客户端可以查看到的本地域名服务器的IP地址是与网络客户端直接通信的本地域名服务器的IP地址,即图1中的第一级本地域名服务器12,而第一级本地域名服务器12的IP地址通常为内网IP。对于第二级本地域名服务器的公网IP地址,在现有技术下,客户端直接无法获得。
图2只是举例说明,在具体实施时,域名系统可以包括两级以上的本地域名服务器。也可以包括一级本地域名服务器,也就是说,与客户端直接相连的本地域名服务器直接连接到权威域名服务器,在此种情况下,上述第一级本地域名服务器和第二级本地域名服务器为同一域名服务器。
为了解决上述问题,本发明实施例提供一种获取本地域名服务器地址的方法,用于获取网络客户端的本地域名服务器的IP地址,值得说明的是,本发明实施例中所描述的获取网络客户端的本地域名服务器的IP地址具体是指获取与权威域名服务器直接通信的本地域名服务器的IP地址。具体地,该方法应用于域名系统中的权威域名服务器,如图2所示,所述方法包括:
S201、接收域名解析请求。
其中,所述域名解析请求是客户端初始发送,并经由客户端与权威域名 服务器之间的本地域名服务器传输至所述权威域名服务器的。
以图1所示的网络系统进行举例说明,所述域名解析请求是由网络客户端11发送至第一级本地域名服务器12,由第一级本地域名服务器12转发至第二级本地域名服务器13,由第二级本地域名服务器13转发至权威域名服务器14(对应上述步骤S201)。其中,图1只是举例说明,在具体实施时,域名系统中可能存在多于两级的本地域名服务器,本发明对此不做限定。
S202、判断所述域名解析请求的类型是否为地址探测类型。
其中,所述地址探测类型是指专用于探测网络客户端的本地域名服务器的IP地址的域名解析请求的类型。
可选地,在具体实施时,可以通过判断所述域名解析请求所请求解析的域名是否为设定域名,来确定所述域名解析请求的类型是否为地址探测类型,其中,若所述域名解析请求所请求解析的域名为所述设定域名,则可确定所述域名解析请求的类型是所述地址探测类型。
示例地,该设定域名可以预先配置在权威域名服务器中,例如,该设定域名可以是:www.example.com。并且,该设定域名可以根据实际需求设定以及修改。这样,权威域名服务器在接收到与其直接通信的本地域名服务器发送的包括域名www.example.com的域名解析请求时,确定该域名解析请求的类型为地址探测类型。
S203、当所述域名解析请求的类型是所述地址探测类型时,从所述域名解析请求中提取第一本地域名服务器的IP地址,所述第一本地域名服务器为向所述权威域名服务器发送所述域名解析请求的域名服务器。
也就是说,所述第一本地域名服务器是与所述权威域名服务器直接通信的本地域名服务器。以图1所示的网络系统进行举例说明,所述的第一本地域名服务器即图1所示的第二级本地域名服务器13。
S204、发送用于响应所述域名解析请求的响应消息,所述响应消息包括 所述第一本地域名服务器的IP地址。
具体地,第一本地域名服务器接收到权威域名服务器发送的响应消息后,将该响应消息发送至下一级的本地域名服务器,以此将所述响应消息返回给客户端。
采用上述方法,对于地址探测类型的域名解析请求,权威域名服务器可以将与其直接通信的本地域名服务器的IP地址返回给客户端,相比现有技术中权威域名服务器在接收到域名解析请求后,将为客户端分配的CDN服务器或者ADN服务器的IP地址返回给客户端,本公开实施例提供的技术方案可以使得客户端能够获知本地域名服务器的IP地址,有利于进一步进行网络问题诊断。
值得说明的是,权威域名服务器是通过发送域名解析请求的本地域名服务器的IP地址来判断客户端所处的网络位置,并返回CDN或ADN网络中离客户端最近CDN或ADN服务器的IP地址,作为域名解析请求的响应。但是,由于全球的网络环境一直在变化中,权威域名服务器中的本地域名服务器IP地址库但是总是会遇到不存在,甚至错误的本地域名服务器IP地址,在此种情况下,客户端可能被引导到一个并非最优的CDN或者ADN服务器,使服务效果变差。因此,通过本发明实施例提供的技术方案,用户在客户端侧获取到本地域名服务器的IP地址后,可以对权威域名服务器的IP地址库进行更新。
也就是说,本发明实施例提供的获取本地域名服务器地址的方法还可以进一步包括:接收用于更新所述权威域名服务器的IP地址库的指令,所述指令包括所述第一本地域名服务器的IP地址以及所述第一本地域名服务器的IP地址对应的网络位置信息;根据所述指令对所述权威域名服务器的IP地址库进行更新。
这样,进一步地,权威域名服务器在接收到所述第一本地域名服务器发 送的第一域名解析请求后,可以判断所述第一域名解析请求的类型是否为所述地址探测类型,并且当所述第一域名解析请求的类型不是所述地址探测类型时,根据所述权威域名服务器更新后的IP地址库确定所述第一本地域名服务器的IP地址对应的网络位置信息,并根据所述网络位置信息分配CDN服务器或者ADN服务器,并发送用于响应所述第一域名解析请求的第一响应消息,所述第一响应消息包括所述CDN服务器或者所述ADN服务器的IP地址。这样,所述第一本地域名服务器可以通过次级的本地域名服务器将所述CDN服务器或者所述ADN服务器的IP地址发送给所述客户端。从而将客户端引导到最优的CDN或者ADN服务器。
另外,用户也可以在客户端侧获取到本地域名服务器的IP地址后,对客户端接入的本地域名服务器进行更改,本发明对比不做限定。
可选地,为了确保权威域名服务器的现有功能不受影响,在步骤S202中,若所述域名解析请求的类型不是所述地址探测类型,可以根据所述权威域名服务器的IP地址库确定对应的网络位置信息,并根据所述网络位置信息为分配内容分发网络CDN服务器或者应用交付网络ADN服务器,并发送用于响应所述域名解析请求的响应消息,所述响应消息包括所述CDN服务器或者所述ADN服务器的IP地址。这样,所述第一本地域名服务器通过次级的本地域名服务器将所述CDN服务器或者所述ADN服务器的IP地址发送给所述客户端。从而实现在不影响权威域名服务器现有功能的前提下,使得客户端能够获取到本地域名服务器的IP地址。
本发明实施例还提供另一种获取本地域名服务器地址的方法,所述方法应用于客户端,如图3所示,所述方法包括:
S301、发送域名解析请求。
S302、接收第二本地域名服务器发送的响应所述域名解析请求的响应消息,所述响应消息包括第一本地域名服务器的IP地址。
其中,所述第二本地域名服务器为接收到所述客户端发送的所述域名解析请求的域名服务器,所述第一本地域名服务器为向权威域名服务器发送所述域名解析请求的域名服务器。
也就是说,所述域名解析请求是客户端发送给第二本地域名服务器并由各级本地域名服务器转发,并最终由第一本地域名服务器发送给所述权威域名服务器的。如图1所示,所述第二本地域名服务器是指图1所示的第一级本地域名服务器12,所述第一本地域名服务器是指图1所示的第二级本地域名服务器13。
S303、展示所述第一本地域名服务器的IP地址。
值得说明的是,本发明对客户端将所述第一本地域名服务器的IP地址展示给用户的方式不做限定,例如,客户端在接收到所述响应消息后,可以通过弹窗的方式将所述第一本地域名服务器的IP地址显示在屏幕上,也可以将第一本地域名服务器的IP地址发送给用户的手持设备。
采用上述方法,用户在不知晓客户端当前接入的本地域名服务器时,可以通过所述客户端访问设定域名,权威域名服务器在接收到请求解析所述设定域名的域名解析请求时,可以将本地域名服务器的IP地址返回至客户端,使得客户端能够获知本地域名服务器的IP地址,有利于进一步进行网络问题诊断。
为了使本领域技术人员更加清楚的理解本发明实施例提供的技术方案,下面以图1所示的网络系统对本发明实施例提供的获取本地域名服务器地址的方法进行说明,如图4所示,该方法包括:
S401、网络客户端11向第一级本地域名服务器12发送域名解析请求。
其中,该域名解析请求包括域名信息。
S402、第一级本地域名服务器12在接收到该域名解析请求后,将该域名解析请求转发给第二级域名服务器13。
S403、第二级域名服务器13在接收到该域名解析请求后,将该域名解析请求转发给权威域名服务器14。
S404、权威域名服务器14判断该域名解析请求的类型是否为地址探测类型。
具体地,该权威域名服务器14中预留有用于专用于探测客户端的本地域名服务器IP地址的域名信息,在接收到该域名解析请求后,权威域名服务器可以比较该域名解析请求中的域名信息是否与预留的域名信息一致,若一致,则确定该域名解析请求的类型为地址探测类型,若不一致,则确定该域名解析请求非地址探测类型。
进一步地,若该域名解析请求的类型不是地址探测类型,则执行步骤S405至S407,若该域名解析请求的类型是地址探测类型,则执行步骤S408至S411。
S405、权威域名服务器14在IP地址库中根据第二级本地域名服务器13的IP地址确定客户端11的网络位置。
S406、权威域名服务器14根据客户端11的网络位置为客户端11分配CDN服务器或者ADN服务器。
S407、权威域名服务器14通过第二级本地域名服务器12以及第二级本地域名服务器11将为客户端11分配的CDN服务器或者ADN服务器的IP地址返回给客户端11。
S408、权威域名服务器14从所述域名解析请求中提取第二级本地域名服务器14的IP地址。
具体地,权威域名服务器14从域名解析请求数据包中提取源IP,此源IP即为客户端的本地域名服务器的IP地址。
S409、权威域名服务器14发送包括所述IP地址的响应消息给第二级本地域名服务器13。
S410、第二级域名服务器13将该响应消息转发给第一级本地域名服务器12。
S411、第一级域名服务器12将该响应消息转发给客户端11。
通过上述方法步骤,对于地址探测类型的域名解析请求,权威域名服务器可以将与其直接通信的本地域名服务器的IP地址返回给客户端,相比现有技术中权威域名服务器在接收到域名解析请求后,将为客户端分配的CDN服务器或者ADN服务器的IP地址返回给客户端,本公开实施例提供的技术方案可以使得客户端能够获知本地域名服务器的IP地址,有利于进一步进行网络问题诊断。
值得说明的是,对于上述方法实施例,为了简单描述,故将其都表述为一系列的动作组合,但是本领域技术人员应该知悉,本发明并不受所描述的动作顺序的限制。其次,本领域技术人员也应该知悉,说明书中所描述的实施例均属于优选实施例,所涉及的动作并不一定是本发明所必须的。
