Explore DNS record types and build a reference DNS table in the browser.
This DNS lookup tool is an educational reference utility for building and reviewing a mock DNS record table in the browser.
It is useful for learning common record types and organizing DNS information, but it does not run live DNS queries against real domains.
Choose the right security utility for passwords, hashes, certificate review, DNS checks, and domain lookups instead of expecting one browser tool to do a full security audit.
A plain-English explanation of SSL/TLS certificates, what they do, why expiry matters, and what a browser lock icon actually represents.
Generate a customized privacy policy for your website or app.
Generate strong, random passwords with customizable length and character types.
Check how strong your password is and get suggestions for improvement.
Review SSL/TLS certificate fields and expiry dates with a browser-based educational checker.
Encrypt and decrypt text using AES, DES, and other encryption algorithms.
Explore how bcrypt hashing works with this interactive simulation — not for production use.
DNS Record Reference Tool
This educational tool lets you explore DNS record types and build a mock DNS table. For live DNS lookups, use tools like dig, nslookup, or online services like dns.google and MXToolbox.
Maps a domain name to an IPv4 address. This is the most fundamental DNS record type, used when a browser needs to find the IP address for a website.
93.184.216.34Maps a domain name to an IPv6 address. Similar to A records but for the newer IPv6 protocol which provides a much larger address space.
2606:2800:220:1:248:1893:25c8:1946Specifies the mail servers responsible for receiving email for the domain. Priority values determine the order in which mail servers are tried (lower = higher priority).
mail.example.com (priority: 10)Creates an alias from one domain name to another. Often used to point subdomains (like www) to the main domain. Cannot coexist with other record types for the same name.
www.example.com -> example.comStores arbitrary text data. Commonly used for SPF (email authentication), DKIM (email signing), DMARC (email policy), domain verification, and other purposes.
v=spf1 include:_spf.google.com ~allSpecifies the authoritative name servers for the domain. These are the servers that hold the actual DNS records and respond to queries for the domain.
ns1.example.comContains administrative information about the domain zone, including the primary name server, the email of the zone administrator, the domain serial number, and timers for refreshing the zone.
ns1.example.com admin.example.com 2024010101 3600 900 604800 86400
