DNS Propagation Checker
NslookupTool.com lets you instantly perform a DNS lookup to check a domain names current IP address and DNS record information against multiple name servers located in different parts of the world.
This allows you to check the current state of DNS propagation after having made changes to your domains records.
A Record |
Returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host, but it is also used for DNSBLs, storing subnet masks in RFC 1101, etc. |
AAAA Record |
Returns a 128-bit IPv6 address, most commonly used to map hostnames to an IP address of the host. |
CNAME Record |
Alias of one name to another: the DNS lookup will continue by retrying the lookup with the new name. |
DKIM Record |
DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect email spoofing. It allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain. It is intended to prevent forged sender addresses in emails, a technique often used in phishing and email spam. |
DMARC Record |
Domain-based Message Authentication, Reporting and Conformance (DMARC) is an email-validation system designed to detect and prevent email spoofing. It is intended to combat certain techniques often used in phishing and email spam, such as emails with forged sender addresses that appear to originate from legitimate organizations. Specified in RFC 7489, DMARC counters the illegitimate usage of the exact domain name in the From: field of email message headers. |
MX Record |
A mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain, and a preference value used to prioritize mail delivery if multiple mail servers are available. The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol (SMTP). |
NS Record |
Delegates a DNS zone to use the given authoritative name servers |
PTR Record |
The PTR record is one of the mail exchange records in the e-mail system; the other mail exchange record is the A record (in the IPv4 protocol) or the AAAA record (in the IPv6 protocol). PTR records are often used for reverse address resolution. |
SOA Record |
Specifies authoritative information about a DNS zone, including the primary name server, the email of the domain administrator, the domain serial number, and several timers relating to refreshing the zone. |
SPF Record |
Sender Policy Framework (SPF) is a simple email-validation system designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain comes from a host authorized by that domain's administrators.[1] The list of authorized sending hosts for a domain is published in the Domain Name System (DNS) records for that domain in the form of a specially formatted TXT record. Email spam and phishing often use forged "from" addresses, so publishing and checking SPF records can be considered anti-spam techniques. |
SRV Record |
A Service record (SRV record) is a specification of data in the Domain Name System defining the location, i.e. the hostname and port number, of servers for specified services. It is defined in RFC 2782, and its type code is 33. Some Internet protocols such as the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP) often require SRV support by network elements. |
TXT Record |
TXT records hold free form text of any type. A fully qualified domain name may have many TXT records. The most common uses for TXT records are Sender Policy Framework (SPF), DomainKeys (DK), and DomainKeys Identified E-mail (DKIM). TXT records historically have also been used to contain human readable information about a server, network, data center, and other accounting information. |
