What are IP addresses and DNS addresses?

What is an IP address? What do IPv4 and IPv6 mean?

How does the internet work? What are DNS, MAC, and IP addresses?

Depending on your settings, if the DHCP function of the router is turned on (generally the default), then the router IP address and DNS will be set to default, and the router will automatically assign it to you; If the router DHCP function is turned off, then the IP address and DNS of the router should be told to you beforehand.

The default IP address of the router can be viewed in the router manual or behind the router.

Shenzhen or, depending on where you are.

IP is your unique identity in the Internet, equivalent to your ID number, DNS is the name server, responsible for the resolution between the domain name and the IP address.

The IP address can be entered into ipcofig by CMD query, which is a kind of identity for surfing the Internet.

DNS is responsible for the resolution between domain names and IP addresses.

There is no necessary connection between the IP and the DNS server. IP is a protocol, and what is actually used is an IP address, which is composed of some numbers. The DNS server is a domain name server, which simply means that in the Internet or WAN, the English ** is converted into a numeric address for resolution.

The following is the specific definition: IP is the foreign language abbreviation of Internet Protocol, and the Chinese abbreviation is "Network Association".The protocol for interconnection between networks is also a protocol designed for computer networks to connect with each other for communication.

In the Internet, it is a set of rules that enable all computer networks connected to the Internet to communicate with each other, and prescribe the rules that computers should follow when communicating on the Internet. Any computer system manufactured by any manufacturer can be interconnected with the Internet as long as it complies with the IP protocol. IP addresses are unique and can be divided into 5 categories depending on the nature of the user.

DNS is an abbreviation for Domain Name System (or Domain Name Service) for computers, which consists of a domain name resolver and a name server. A name server is a server that stores the domain names and corresponding IP addresses of all hosts in the network and has the function of converting domain names to IP addresses. The domain name must correspond to an IP address, and a domain name can have multiple IP addresses, and the IP address does not necessarily have a domain name.

The Domain Name System uses a hierarchical structure similar to a directory tree. Nameservers are client servers on the server side of the server pattern, and there are two main forms: primary servers and servers.

The process of mapping a domain name to an IP address is known as domain name resolution.

1. IP address refers to the Internet Protocol address (English: Internet Protocol Address) is mainly used to identify network devices on the Internet, and each device that can access the Internet has its own IP address.

IPv4 Introduction:

IPv4 is an abbreviation for Internet Protocol Version 4, where Internet Protocol is translated as "Internet Protocol". IPv4 specifies that the IP address length is 32 bits, i.e. there are 2 32 addresses.

IPv6 Introduction:

IPv6 is an abbreviation for Internet Protocol Version 6, where Internet Protocol is translated as "Internet Protocol". IPv6 stipulates that the length of IP addresses is 128 bits, i.e. there are 2 128 addresses, and IPv6 came into existence to solve the problem of the depletion of the IPv4 address pool.

3. IP addresses are divided into:"Host bits"and Network Bits

2. DNS resolution is divided into: forward search area and reverse search area.

The forward lookup zone resolves the hostname (domain name) to the IP

The reverse lookup zone resolves the IP address to the hostname (domain name).

Check whether the router has been dialed up, whether the WAN port in the running state has obtained IP and other parameters, and check whether the IP and DNS of the local connection are automatically obtained.

What is an IP address? The IP address is the same as a person's ID card. An IP address represents a network.

DNS is used to resolve domain names.

IP is the house, DNS is the house built by whom.
