Talking about the domain name analysis

Small series said before how to register their own domain name and domain name for the record, today small series on the name after the registration of how to do parsing it.

What is domain name resolution?

Domain name resolution is the domain name to the IP address of the conversion process. Domain name is to facilitate the memory of the establishment of a set of address conversion system, users want to access the Internet above the server, or must be implemented through IP address, and http://www.aliyun.com/zixun/aggregation/12499. HTML > Domain Resolution is the process of converting domain names to IP addresses, and domain name parsing is done by intelligent DNS servers.

What is IP reverse parsing?

There are two zones in the DNS server, that is, "forward lookup zone" and "Reverse lookup zone", the forward lookup zone is the small part of the domain name resolution, the reverse lookup zone is IP reverse resolution, its role is to query the IP address of the PTR record to get the IP address to the domain name, of course, A PTR record of the IP address is required to successfully obtain a domain name. A PTR record is a kind of mail exchange record in which a record and a PTR record are recorded, a record resolves a name to an address, and a PTR record resolves an address to a name. Address refers to the IP address of a client, whose name refers to a fully qualified domain name of a customer. PTR records through the query, to achieve the purpose of the reverse search, which is why we can use IP address to find the domain name whois information reasons.

What's a record?

A (address) record is a record of IP addresses that specifies the host name (or domain name). Users can point to the site server under this domain name to their own Web server. You can also set your domain two domain name.

What is an MX record?

Message routing records, the user can point to the mail server under the domain name on their mail servers, and then control all mailbox settings themselves. You simply fill in your server's IP address online, you can send all the mail under your domain to your own set up the corresponding mail server.

The function of the reverse Domain name resolution system (Reverse DNS) ensures that the appropriate mail exchange records are in effect. This is one of the most common problems (especially in foreign mail systems). More e-mail providers use a reverse domain Resolution system lookup to confirm where the information comes from. Because the use of this approach becomes more extensive, domains that do not correctly publish reverse Domain name resolution system Information may have more frequent mail returns. Therefore, when the domain name resolution is completed, you should also apply to your line access provider (ISP) for reverse address resolution, especially foreign-related corporate mail, in order to reduce the possibility of withdrawal by foreign agencies.

Reverse Domain name resolution verification is actually the other server in progress, if we do not do the reverse parsing, then the opposite side of the server's reverse parsing verification will fail, so that the other server will be we are unknown to the sender to reject the message we sent, which is that we exclude other reasons (such as by the other side blacklisted, The reason that there is no MX record, a dynamic IP address, and so on, that cannot be sent to the mail server without a reverse resolution.

I believe that after the small series of this explanation, it should be the domain name resolution has a general understanding of it, it is hoped that everyone registered domain name after you remember to go to the domain name resolution OH.
