Description

Domain name resolution method and device

technical field

The invention relates to Internet technology, in particular to a domain name resolution method and device.

Background technique

The Domain Name System (DNS for short) is a distributed database that maps domain names and IP addresses to each other on the Internet. When a user uses an electronic device to access the host of other servers on the Internet, the DNS server converts the domain name of the host entered by the user into the Internet Protocol (Internet Protocol, referred to as: IP) address of the host, so that the user can access the Internet more conveniently. Among them, the user does not need to remember the IP address number string of the host name, but directly enters the domain name of the host on the electronic device, and can directly access the host of other servers through the domain name of the host.

In the prior art, since the electronic device needs to send the domain name to the DNS server every time the user inputs the domain name, the DNS server converts the domain name into an IP address and returns the IP address to the electronic device. The RFC standard of DNS defines the local DNS cache library of the electronic device. Every time the electronic device sends the domain name to the DNS server and receives the IP address, the corresponding relationship between the domain name and the IP address is stored in the local DNS cache library. When the user enters the domain name again, the corresponding relationship between the domain name and the IP address is first searched in the local DNS cache library, so as to reduce frequent independent communications between the electronic device and the DNS server.

With the existing technology, since different users frequently visit different domain names, when a user changes an electronic device or different users use the same electronic device, the electronic device still needs to communicate frequently with the DNS server.

The technical solution of the present invention will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 1 is a schematic flowchart of Embodiment 1 of the domain name resolution method of the present invention. As shown in Figure 1, the domain name resolution method of this embodiment includes:

S101: Obtain the DNS record of the user from the Domain Name System DNS server, and store the DNS record. The DNS record includes a one-to-one correspondence between N domain names and N network protocol IP addresses, where N is an integer greater than 0.

Specifically, the subject executed in this embodiment may be any electronic device capable of connecting to the Internet. For example: mobile phone, tablet or computer, etc. This step S101 may be executed by the electronic device when the user first connects to the Internet through the electronic device. After the user connects to the Internet through the electronic device, the user's DNS record is obtained from the DNS server, and the DNS record is stored in the user's DNS cache library in the electronic device. The DNS record includes a one-to-one correspondence between N domain names and N network protocol IP addresses, where N is an integer greater than 0.

Optionally, the DNS records may include, for example, the top N domain names and IP addresses that conform to the user's usage habits, that is, the most frequently visited by the user. For example: the DNS server stores the DNS records of all registered users, and assigns a user name and password to each user. When the first user uses the mobile phone, after logging in to the DNS server with his user name and password through the mobile phone, the mobile phone obtains the DNS record of the first user from the DNS server and stores it in the storage space of the mobile phone. The first user's DNS records include, for example, the first 100 most frequently accessed DNS records when the first user uses other electronic devices to access the Internet, that is, the one-to-one correspondence between 100 domain names and 100 network protocol IP addresses. It should be noted that this embodiment is not limited thereto.

S102: When the first domain name input by the user is obtained, according to the DNS record, obtain the first IP address corresponding to the first domain name.

Specifically, when the electronic device acquires the first domain name input by the user, that is, the user wishes to access content at the first IP address corresponding to the first domain name. Then the electronic device acquires the first IP address corresponding to the first domain name from the DNS record according to the DNS record acquired in S101. Since the DNS record is related to the user, the DNS record can be understood as a user-level database. If the first domain name entered by the user is in the DNS record, the electronic device directly obtains the first IP address corresponding to the first domain name from the DNS record. , instead of sending the first domain name to the DNS server and the DNS server resolves the first domain name to obtain the first IP address, thereby reducing the frequent communication between the electronic device and the DNS server, saving resource consumption, and improving the efficiency of the server, that is, the electronic The speed at which the device accesses the first IP address.

FIG. 2 is a schematic flowchart of Embodiment 2 of the domain name resolution method of the present invention. As shown in Figure 2, this embodiment includes:

S201: When the N domain names in the DNS record include the first domain name, obtain the first IP address corresponding to the first domain name from the DNS record.

Specifically, if the N domain names in the DNS record include the first domain name input by the user, the electronic device directly acquires the first IP address corresponding to the first domain name from the DNS record.

S202: When the N domain names in the DNS record do not include the first domain name, send a domain name resolution request to the DNS server, where the domain name resolution request includes the first domain name.

Specifically, S202 and S201 are a parallel solution. If the N domain names in the DNS record do not include the first domain name, the electronic device sends the first domain name to the DNS server through a domain name resolution request, so that the DNS server on the network side resolves the first domain name. The domain name gets the first IP address.

S203: Receive the first IP address sent by the DNS server.

Specifically, after the DNS server resolves the first domain name to obtain the first IP address, it sends the first IP address to the electronic device. The electronic device receives and obtains the first IP address sent by the DNS server.

Further, in the above embodiment, after S203, it also includes: storing the correspondence between the first domain name and the first IP address; when the DNS record update time arrives, sending the correspondence between the first domain name and the first IP address to the DNS server, so that the DNS server updates the user's DNS record according to the correspondence between the first domain name and the first IP address.

Wherein, if the N domain names in the DNS record do not include the first domain name, then after S203, the first domain name accessed by the user, that is, the domain name not in the DNS record is stored in the local storage unit of the electronic device, and the first domain name is stored at the same time Corresponding relationship with the first IP address. And when the DNS record update time arrives, the corresponding relationship between the first domain name and the first IP address is sent to the DNS server, so that the DNS server updates the DNS record of the user according to the corresponding relationship between the first domain name and the first IP address. Optionally, the DNS record update time can be one hour or one day.

Further, in the above embodiments, it also includes:

When the first update time arrives, the access record of the first domain name is sent to the DNS server, so that the DNS server updates the DNS record of the user according to the access record of the first domain name and the correspondence between the first domain name and the first IP address.

For example: when the first update time arrives, send all the access records of the first domain name accessed by the user within the first time period to the DNS server, so that the DNS server can The corresponding relationship between addresses updates the user's DNS records. Wherein, the access record includes the access cycle, access habits and/or access times of the user accessing the first domain name.

Further, in the above embodiments, it also includes:

When the second update time arrives, the updated DNS record sent by the DNS server is received.

For example: when the second update time arrives, the DNS server sends the updated DNS record to the electronic device, and the electronic device receives the updated DNS record sent by the DNS server.

Optionally, in each of the above embodiments, if the first domain name entered by the user is not included in the N domain names of the DNS record, the first domain name may be obtained from a DNS cache library that complies with the RFC (Request For Comments) standard. For the first IP address, if the DNS cache still does not include the first domain name, then send the first domain name to the DNS server, so that the DNS server can resolve the first domain name to obtain the first IP address.
