Checking DNS records for a domain
Gets information about DNS resource records for a domain name.DNS – is a domain name system for obtaining information about domains. Most often used to obtain an IP address from a domain name.
Main (frequently used) post types:- A – This is an address record used to match between a domain name and the IP address (IPv4) of the server
- AAAA – Address record, used to match between a domain name and the IP address (IPv6) of the server
- CNAME – Canonical name for alias
- MX – Mail gateway address for the domain. Consists of two parts, priority (the higher the number, the lower the priority), and the node address. With its help, the mail agent, when sending emails to a specific domain, understands which server to forward to.
- NS – Address of the node responsible for the domain zone. Critical to the functioning of the domain name system itself.
- TXT – Recording arbitrary data. Very often used for SPF, it allows the domain owner to specify a list of servers that have the right to send email messages with return addresses in this domain. Also for DKIM – E-mail authentication method designed to detect forgery of messages sent by email. The method allows the recipient to verify that the letter was actually sent from the declared domain. DKIM makes it easier to combat spoofed sender addresses, which are often used in phishing emails and spam emails.
If you want to check some specific TXT records for a domain, for example TXT record for DKIM, then before the domain you should add the value of the Host field for this TXT record. For example, if mail._domainkey is written there, then to obtain this entry for the domain yandex.ru it will look like this mail._domainkey.yandex.ru
