Problems solved by technology

[0003] When it is necessary to customize the domain name resolution of the cloud host in the virtual private cloud, it is necessary to configure the domain name and the IP address corresponding to the domain name in the host file of the cloud host. If there is a domain name that matches the domain name requested by the cloud host, the IP address corresponding to the domain name is obtained from the host file, and then the cloud host directly accesses the IP address. In this way, when accessing the virtual private cloud When all cloud hosts perform custom domain name resolution, the host files of all cloud hosts need to be modified. When the number of cloud hosts in the virtual private cloud is large, the workload of modifying the host files of all cloud hosts is large, and it is not flexible Customize domain name resolution for a single cloud host, multiple cloud hosts or the entire virtual private cloud system

Abstract

The invention relates to the field of domain name resolution and provides a domain name resolution method and a related device. The domain name resolution method comprises steps: when a cloud host initiates a domain name resolution request, a virtual private cloud gateway receives a first domain name resolution request message sent by the cloud host, wherein the first domain name resolution request message carries the domain name requested to be accessed by the cloud host; the virtual private cloud gateway finds out whether a first domain name matched with the domain name requested to be accessed by the cloud host exists in domain name resolution flow table data in a centralized controller; if the first domain name exists, the virtual private cloud gateway acquires a first IP address corresponding to the first domain name from the domain name resolution flow table data in the centralized controller; and the virtual private cloud gateway sends a first domain name resolution response message to the cloud host, wherein the first domain name resolution response message carries the first IP address. In the technical scheme provided by the embodiment of the invention, customized domain name resolution can be flexibly carried out on the cloud host in the virtual private cloud.

Description

technical field [0001] The invention relates to the field of domain name resolution, in particular to a domain name resolution method and a related device. Background technique [0002] With the continuous maturity of virtualization and cloud computing technology, more and more cloud computing vendors begin to provide virtual private cloud services. At present, the domain name resolution solutions of cloud computing vendors all adopt centralized domain name resolution. Cloud hosts share a set of centralized domain name resolution servers. [0003] When it is necessary to customize the domain name resolution of the cloud host in the virtual private cloud, it is necessary to configure the domain name and the IP address corresponding to the domain name in the host file of the cloud host. If there is a domain name that matches the domain name requested by the cloud host, the IP address corresponding to the domain name is obtained from the host file, and then the cloud host dire...
