How do I read DNS records?

POP (port opening protocol) is in essence a DNS lookup. The client asks the name server, "What IP address can I resolve the name of the host?" The DNS lookup has to know three things for every hostname/IP combination: what is the hostname? where can I find this? is this OK? POP doesn't go over IP addresses. It goes over network addresses and looks for an ARPA connection to a specified destination. If there isn't one it defaults to 127.0.1, the loopback interface. That's because when you're at 127.1, there's nothing but yourself on the loopback interface to send the message to.

So you need a recursive DNS server configured and you need some clients with POP running. And to be actually useful you should configure the domain to have several entries for all the DNS servers so you'll be able to resolve all the sub-domains.

What are DNS records for dummies?

What is meant by Domain Name System records? These terms are usually synonymous. Who should learn DNS records? You can use DNS records to understand a host or any software on the network. If you are working with a computer or a software, the main objective is to configure your system to connect to various websites and computers. DNS makes this possible. You should know the terms associated with the DNS records. This will help you to understand the way the records work and how to configure the DNS.

In this post, we will discuss about the basic concepts of the DNS. Then, we will go through some of the basic configurations available in a typical network. Lastly, we will mention some of the common problems with DNS records and their solution.

DNS records are very simple to understand. However, it requires the understanding of some important concepts before we look at the simple examples that are given below. The following diagram shows the major components involved in the configuration of DNS.

What is DNS? The acronym DNS stands for Domain Name System. DNS records are the records used to set up the connection between the system on the network and the name servers. The primary task of DNS is to convert the host names into an IP address. The DNS records are mostly of two types: A Record and CNAME Record. What are A Records? The A record stands for the host name that is assigned to a specific IP address. For example, the A record for www.google.com is set up like so:

A google.com This record tells that the IP address for www.com is 127.0. However, the host www.com is mapped to 127.

However, it doesn't tell that www.com actually resolves to the IP address of 127. It is a common misconception that www.com can be resolved directly to the IP address of 127. That's not the case. If you try to resolve google.com or google.com:80 or google.com:443, they will not directly resolve to 127.

What are the four types of DNS records?

Let's first go over the four DNS record types: A - IPv4 addresses.

AAAA - IPv6 addresses. CNAME - CNAME records. MX - Mail eXchange record. The A record is a standard DNS record and is made up of a host name (an IP address) and a text string. The AAAA record is a special record type for IPv6 addresses, and the CNAME record is a link between two different names (an A record is not considered a link because it is a single name). Finally, the MX record is an important record that contains information about an e-mail server.

The following diagram shows all these DNS record types in their proper place. It's important to note that these are the only four record types in the DNS standard. There are no other record types.

How do I view my DNS records? By default, you can view your DNS records using the dig command. You will need to know the IP address of the machine hosting your web site, and you should be able to find this out by searching Google.

For example, if your web site is hosted on a Linux machine with the hostname mysite.10.3-P1 <<>> mysite. IN A ;; ANSWER SECTION: mysite. 3600 IN A 104.16.1 ;; Query time: 13 msec ;; SERVER: 192.168.
