Domain Name Correction System

The domain name error correction system mainly includes domain name resolution, domain name resolution server, domain name cache, domain name resolution strategy and domain name system security. Detailed introduction: 1. Domain name resolution is the process of converting domain names into IP addresses; 2. Domain name resolution server is a server that stores the correspondence between domain names and IP addresses; 3. Domain name cache is a data structure that stores domain name resolution results; 4. Domain name resolution policy is a method that stipulates the domain name resolution process Behavior and rule strategies; 5. Domain name system security, etc.

What are the domain name error correction systems?

Domain Name System (DNS) is a distributed naming system on the Internet that is used to resolve domain names into IP addresses. It does this by combining the domain name with the IP Addresses are associated to make it easier for users to access the Internet. When a user enters a URL into a browser, the DNS server automatically resolves the URL into an IP address, and then connect the user to the corresponding website.

The domain name error correction system mainly includes the following aspects:

1. Domain name resolution: Domain name resolution is the process of converting domain names into IP addresses. When a user enters a URL into a browser, the DNS server looks for the IP corresponding to the URL address and then connects the user to the website. Domain name resolution is usually completed through recursive query (Recursive Query) or iterative query (Iterative Query). Recursive query means The DNS server directly initiates a query to the root domain name server (Root DNS Server); iterative query means that the DNS server first queries the local domain name server (Local DNS Server) initiates a query. If the local domain name server cannot find the answer, it initiates a query to the root domain name server.

2. Domain name resolution server: Domain name resolution server (Domain Name Server, abbreviation: DNS Server) is a kind of storage domain name and IP The server of the address correspondence. It is responsible for resolving domain names into IP addresses, or IP addresses into domain names. Domain name resolution servers are usually deployed by Internet Service Providers (ISPs) or enterprises themselves.

3. Domain Name Cache: Domain Name Cache is a data structure that stores domain name resolution results. When a user visits a website, DNS The server will store the domain name resolution results of the website in the domain name cache so that the next time the user visits, the corresponding IP address can be obtained faster. Domain name caching can increase the speed of domain name resolution and reduce network latency.

4. Domain Name Resolution Strategy: Domain Name Resolution Policy) is a policy that stipulates behaviors and rules in the domain name resolution process. Domain name resolution strategies usually include the following:

Preferred DNS Server: When a user initiates a domain name resolution request, DNS The server will first query the preferred resolution server. If the preferred parsing server cannot find the answer, other parsing servers are queried.

Alternate DNS Server: When the preferred resolution server cannot be accessed or returns an incorrect answer, DNS The server queries an alternate resolution server. Backup resolution servers are usually domain name resolution servers of other network service providers or enterprises.

Authoritative DNS Server: The authoritative DNS server is a domain name resolution server responsible for managing a specific domain name. It knows the exact IP of the domain name address and can return correct parsing results.

5. Domain Name System Security: Domain Name System Security Security (abbreviation: DNSSEC) is a security technology used to protect the domain name system from attacks and tampering. DNSSEC Verify the integrity and authenticity of domain name resolution results by using digital signatures, encryption, and certificates. It prevents malicious users from forging domain name resolution results, thereby protecting users from phishing and other cyber attacks.

In short, the domain name correction system is an important infrastructure in the Internet, which allows users to access the Internet conveniently. The domain name error correction system mainly includes domain name resolution, domain name resolution server, domain name cache, domain name resolution strategy and domain name system security. With the continuous development of the Internet, domain name error correction systems will play an increasingly important role in the future.
