DNS is global network that maps IP addresses to names such as domains. When a computer or mobile device makes a DNS query, the information is passed to DNS servers and resolvers to translate names into addresses. DNS relies on a number different record types which are responsible for specific functions in order to carry out this process.
A- and AAAA-records are the most popular record types. These records map domain names with IP addresses in both IPv4 & IPv6 networks. These are a vital part of the internet's infrastructure and are used to connect hosts together across networks, so knowing how these records work can help you keep your business connected.
There are many DNS records and knowing them will help you to better understand the operation of your network. Getting familiar with them can also help you identify security threats and troubleshoot issues on your network.
NS record is one of the important DNS records. It indicates the name servers that are associated with your domain. This reduces time for your visitors in finding your website.
DNAME record: These records are similar to CNAME records, but they allow multiple alias domains to be stored in a single CNAME record. The value field of the CNAME record must contain the real domain name of the alias domain, while the TTL value is set to a time frame until it expires.
PTR record : The PTR allows domains to perform reverse-lookups. You can use this to see if the domain you are looking for is active.
MX record: You can use this type of record to find out the primary server for a specific domain or subdomain. This is a simple way to check the validity of a particular mail server and it can help prevent spoofing.
TXT record : This is a text record that can be used for machine-readable information, such as security and abuse prevention data. Email applications often use this feature to filter messages according to spam or malware-detection algorithms.
SOA record: Another essential DNS record, this one contains all the important information about a zone. It includes details such as the name servers for a zone, email addresses of contact, default TTL and more.
The SRV Record is another record that is important for a particular domain. This record allows for dynamically creating URIs of specific services within a host.
RRSIG: This is the record that contains digital signings to authenticate DNS resources records in accordance DNSSEC protocols. It is also called the RP record, and contains the email address of the person responsible for the domain.
A record: The most common type of record. This record maps domain names to IPv4 address, making it a useful tool to manage your network and ensure your users are able to connect to your website.
