What is Tietong IP address and DNS address

Because of the limited IP address resources, Tietong uses the national dynamic IP sharing, which is often changed, and it is impossible to say, while Telecom and Unicom share the IP address of the whole city, and one city uses one.

One. Tietong has thousands of IP addresses and doesn't know how to give them to you. Two. The DNS is as follows.

The DNS server address is different from place to place, and each region has multiple DNS server addresses to choose from.

In fact, you don't have to be limited to the DNS of regional operators, you can also try domestic public DNS resolution (e.g., 114, etc.).

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 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 called"Domain name resolution"。

The DNS server address varies from place to place, and there are multiple DNS server addresses to choose from in each region.

Each operator has its own DNS server, generally without a router, if it is PPPoE authentication (broadband dial-up), there is no need to fill in the IP address and default gateway, because in the authentication process, the operator's authentication server will automatically assign IP and DNS addresses to the user.

You can click Start-Run-Enter cmd-command ipconfig all to see the DNS server address and find the DNS severs....That's right.,If it's not a LAN.,And there's adsl dial-up Internet filling in doesn't matter.,If you want to fill in the IP address:Subnet mask:

The DNS is different in different places, I know this, but is their DNS still the same if the bandwidth is different? Please be able to list the DNS address of the whole country, to be divided into telecom, Unicom, Netcom, Tietong, thank you, if there is no router, how to fill in the IP address and default gateway. Or you can't fill it in by yourself, and you have to automatically assign it above (telecommunications).

It's not the same, and it's different from city to city.

You can directly telecom dns or china com dns
