DNS Records of NameServers

About Fetch DNS Records of NameServers Tool

The tool fetches DNS records of each nameserver. The DNS records of nameservers help web admins identify whether the nameservers' DNS records have been propagated correctly or not.

What is a nameserver?

With the short abbreviation NS, Nameserver is the type of DNS server that stores all domain DNS records, including A records, MX records, CNAME records, etc.

All the domains that are on the internet rely on multiple nameservers. Suppose if one goes down, that second one is available to solve the DNS query.

Usually, there is one primary nameserver with several secondary nameservers at the back that stores the exact copy of the DNS records as of the primary nameservers.

Nameservers are the hosts specified at the registrar level. These hosts keep a record of all DNS records of a domain.

Different types of DNS records of nameservers

The DNS records provide essential information about the domain or hostname, particularly about its IP address and how to handle the requests for that domain. The most common DNS records type are

• A record, also known as a DNS host record, is the address mapping record that maps the hostname to its corresponding IPv4 address.
• AAAA record is the IPv6 address record that maps the hostname to its corresponding IPv6 address.
• CNAME record is theCanonical Name record that alias a hostname to another hostname.
• MX record is also known as Mail Exchange Record, which specifies an SMTP email server for the host to route outgoing emails to an email server. For detailed analysis, use MX Record Lookup.
• NS record indicates the authoritative nameserver delegated to a specific hostname. It also provides the address of the nameserver. Use NS Lookup Tool for detailed analysis.
• PTR record is the pointer record or reverse DNS record used for reverse IP lookup. It maps the IP address to hostname.
• SRV record is a service location record, like MX, but for other communication protocols. For example, Extensible Messaging and Presence Protocol (XMPP) and the Session Initiation Protocol (SIP) often require SRV records.
• SOA record starts the authority record that appears at the beginning of a DNS zone file. It indicates the authoritative nameserver for the current DNS zone, contact details for the domain administrator, domain serial number, and how frequently DNS information for this zone should be refreshed.
• TXT record allows the website's administrator to insert any arbitrary text in the DNS record, such as opportunistic encryption, SPF, DKIM, DMARC, etc.
• CAA record is also known as Certification Authority Authorization record that stores encryption certificates—PKIX, SPKI, PGP, etc.
• DNSKEY record contains the public key used to verify the Domain Name System Security Extension (DNSSEC) signatures. For detailed analysis use DNSKEY Lookup
