    • A method of correlating nameserver addresses is implemented in a multi-tier name server hierarchy comprising a first level authority for a domain, and one or more second level authorities to which the first level authority delegates with respect to a particular sub-domain associated with the domain. Preferably, the first level authority is IPv4-based and at least one second level authority is IPv6-based. The first level authority responds to a request issued by a client caching nameserver (a “CCNS”) and returns an answer that includes both IPv4 and IPv6 authorities for the domain. The CCNS is located at an IPv4 source address that is passed along to the first level authority with the CCNS request. According to a feature of this disclosure, the first level authority encodes the CCNS IPv4 source address in the IPv6 destination address of at least one IPv6 authority. Then, when the CCNS then makes a follow-on IPv6 request (with respect to the sub-domain) directed to the IPv6 authority, the IPv6 authority knows both the IPv6 address of the CCNS (by virtue of having received it in association with the request) as well as its IPv4 address (by virtue of the encoding). The IPv6 authority maintains the IPv4-IPv6 correlation. Over time (i.e., as other CCNSs make requests), the IPv6 authority builds up a database of these CCNS IPv6-IPv4 associations.
    • 关联名称服务器地址的方法在包括域的第一级权限的多层名称服务器层级中实现,以及一个或多个第二级权限,第一级权限相对于与该属性相关联的特定子域 域。 优选地,第一级权限是基于IPv4的,并且至少一个第二级权限是基于IPv6的。 第一级权限响应客户端缓存名称服务器(“CCNS”)发出的请求,并返回包含域的IPv4和IPv6权限的答案。 CCNS位于通过CCNS请求传递给第一级权限的IPv4源地址。 根据本公开的特征,第一级权限对至少一个IPv6授权的IPv6目的地址中的CCNS IPv4源地址进行编码。 然后,当CCNS然后对IPv6机构进行后续IPv6请求(相对于子域)时,IPv6授权机构知道CCNS的IPv6地址(凭借与 请求)以及其IPv4地址(通过编码)。 IPv6权限维护IPv4-IPv6相关性。 随着时间的推移(即像其他CCNS发出请求一样),IPv6授权机构建立了这些CCNS IPv6-IPv4关联的数据库。
