The method includes: intercepting a domain name query request sent by a recursive server to a root server, parsing the domain name query request information to determine the target top-level domain (TLD) that the recursive server needs to query; matching the target TLD with multiple preset TLDs to obtain a matching result; when the matching result indicates a successful match, determining the target TLD configuration parameters corresponding to the target TLD based on the mapping relationship between the preset TLDs and preset TLD configuration parameters; generating domain name response information corresponding to the target TLD based on the target TLD configuration parameters and the domain name query request information, and sending the domain name response information to the recursive server. Thus, by intercepting the domain name query request information sent to the root server, processing and generating the domain name response information and returning it, the root server is protected to achieve protection of the TLD.

The present disclosure provides a domain name resolution method and device, related equipment, wherein the method comprises: searching for a root area file corresponding to a target domain name from a root peer node of a blockchain domain name resolution network when the client resolves the target domain name, wherein the root area file includes top-level domain name (TLD) information and a hash value in the target domain name; the blockchain domain name resolution network includes a root peer node and an authoritative peer node; verifying the root area file based on a public key corresponding to the target domain name obtained from the client; obtaining a sub-area file from an authoritative peer node matching the hash value if the verification is passed; and resolving an IP address corresponding to the target domain name from a resource record set in the sub-area file. In the present application, since the hash value in the root area file corresponds to the sub-area file one by one, the consistency of the root area and the sub-area data storage is ensured, thereby ensuring the consistency of the resource record set.

The method comprises the following steps: a node domain name server sends a first domain name resolution request; the intranet authoritative domain name server judges whether the first domain name resolution request is in a first resolution range, if the first domain name resolution request is in the first resolution range, a first IP address is obtained, and if the first domain name resolution request is not in the first resolution range, a second domain name resolution request is sent; the data center domain name server judges whether the second domain name resolution request is in a second resolution range or not, if the second domain name resolution request is in the second resolution range, a second IP address is generated, and if the second domain name resolution request is not in the second resolution range, a third domain name resolution request is sent; and the intranet top-level domain name server searches the target domain name server according to the third domain name resolution request to generate a third IP address. The problems that in the prior art, a domain name server does not have a multi-level link and switching function, the resolution time is long, and the reliability is low are at least solved. The method is suitable for scenes such as enterprise private cloud domain name resolution.
