How do I get a list of DNS records for a domain?

DNS lookups are done by querying DNS servers.

You can use the dig tool to query a DNS server directly: dig @your-dns-server www.google.com
If you want to get the entire domain name, you can use the -x flag to tell dig to print the entire record: dig @your-dns-server -x www.com In addition, you can use the --trace-int flag to print the entire route table as well, which will give you a list of IP addresses that a query might take. Dig @your-dns-server --trace-int www.com If you're interested in what your own DNS resolver is doing when it queries external DNS servers (and not just for www.com), you can use the -x flag of the dig command.

For example: dig -x www.com will print out the entire XML response from Google's DNS servers. Here's a more in-depth explanation of how dig works.

What are the 8 DNS records?

DNS is the name service provider.

It provides a mapping between domain name and IP address, which is also called hostname and is generally a human-readable alias. The first three letters (TLD) of an FQDN (Fully Qualified Domain Name) is used to resolve the domain name to its IP address, and is called its registry. Every Internet domain name must have at least one name server assigned to it. There can be any number of name servers in a domain. A domain can have multiple name servers. A domain can have any number of name servers within that domain. The four letters (TLD) of a FQDN is the top-level domain name, for example: example.com The DNS root zone exists only for backward compatibility and contains no other zones. There are several standard and non-standard zones. There are many DNS zones that have not been added to DNS root servers. The purpose of the DNS zones is to separate and group information into regions. The DNS zone files are structured like hierarchical folders. The first zone with a certain type is located at the base of the hierarchy. Each zone contains one or more zonefiles. Each zone file can contain several zone records. Domain Name and Organization: There are two parts of the domain name, that is first three letters or the second three letters. First three letters (TLD) - These 3 letters are called Top Level Domain. These 3 letters are called Top Level Domain. Second three letters (top-level-domain) - The third three letters after the TLD is called top-level-domain.

If there is a .com in the first three letters, then the domain is called ".com". If there is no second three letters, then the domain is just ".

If there is a country code (.ca for Canada) before the ".com", then the domain is ".ca". If there is a second three letters (.net) after the country code (.ca), then the domain is ".

Organizations also use this kind of names for their domain names.

What are five DNS record types?

DNS record types are the mechanisms that allow you to use the same host name for more than one purpose.

Every host name can have zero or more DNS record types, and these record types tell the DNS server how to resolve a name. The five DNS record types you need to be aware of are:

A (Address Record). CNAME (Canonical Name Record). MX (Mail Exchanger Record). NAPTR (Network Access Protocol Transmission Record). PTR (Pointer Record). Each type has its own characteristics and uses. For example, the A record is the most common DNS record type and holds the name and address for the host or service. A record is useful if you want to know the IP address of a host, or the URL of a website.

MX records are used by email servers to tell which mail server should handle an email message. If you have a website that offers email services (mail.com), you would enter an MX record that points to the mail server for example.

NAPTR records are used to transfer data between network nodes. NAPTR allows you to find the network address of the node on a network by resolving the network address into an IP address. For example, the NAPTR record for a specific website would be www.

The PTR record is used to indicate a specific IP address for a host, but the information in the PTR record is not necessarily for the same host that is defined in the A record. Example. You can see how this works in the following example. Let's say you have a website at example.com and a mail server at mail. We also want to find the IP address of the mail server. To find the IP address of mail.com, we first resolve the name mail.com to an IP address using the MX record. Next, we find the address for the mail server using the PTR record.com MX mail.
