What DNS record types can I check with this tool?

This tool supports A, AAAA, MX, NS, TXT, CNAME, and SOA record lookups for any domain name in real-time.

An A record maps a domain name to an IPv4 address. It tells browsers and servers the exact IP address where the domain is hosted.

What is an MX record?

An MX (Mail Exchange) record specifies the mail servers responsible for receiving emails on behalf of the domain. Lower priority values indicate higher preference.

What is a TXT record used for?

TXT records store text-based information for a domain. They are commonly used for domain ownership verification, SPF (Sender Policy Framework), DKIM email authentication, and DMARC policies.

Why are DNS records not updating after I made changes?

DNS changes take time to propagate across the internet, a process known as DNS propagation. The TTL (Time To Live) value on each record determines how long it is cached. Full propagation can take anywhere from a few minutes to 48 hours depending on your TTL settings and ISP caches.

TTL stands for Time To Live. It is a value (in seconds) that tells DNS resolvers how long to cache a DNS record before checking for updates. A lower TTL means changes propagate faster but increases DNS query load.

DNS Lookup Tool

Instantly lookup A, AAAA, MX, NS, TXT, CNAME, SOA and all other DNS records for any domain — free, real-time, no login needed.

What Is a DNS Lookup?

A DNS Lookup is the process of querying the Domain Name System to retrieve records linked to a domain name. Think of DNS as the internet's phone book — it translates human-readable domain names like example.com into machine-readable IP addresses and other routing information that servers use to deliver content, route emails, and verify domain ownership.

When you enter a domain into this tool, it sends a real-time query to global DNS resolvers and returns all publicly available records — exactly what any mail server, browser, or network engineer would see.

How Does This DNS Lookup Tool Work?

When you enter a domain (e.g. blinkai.co) and click Lookup, the tool sends a DNS query to a recursive resolver, which contacts the authoritative name servers for that domain and retrieves all available public records. Results are returned in real-time and reflect the domain's live DNS configuration at that exact moment.

This is especially useful for:

Verifying DNS changes after updating records at your registrar
Diagnosing email delivery issues via MX record inspection
Confirming domain ownership TXT records (e.g. Google, Microsoft verification)
Auditing name server configurations for security and redundancy
Checking TTL values before and after DNS migrations

DNS Record Types Explained

A Record — Maps a domain name to an IPv4 address. The most fundamental DNS record; tells browsers which server to connect to.
AAAA Record — Same as an A record but for IPv6 addresses. Used when a server supports the newer 128-bit address format.
MX Record — Specifies mail servers responsible for receiving email for the domain. Includes a priority value — lower number means higher priority.
NS Record — Lists the authoritative name servers for the domain. These are the servers responsible for all DNS records in the domain's zone.
TXT Record — Stores arbitrary text. Widely used for domain verification, SPF, DKIM, and DMARC email authentication policies.
CNAME Record — Canonical Name record. Points one domain name to another (an alias), useful for subdomains like www.
SOA Record — Start of Authority. Contains administrative information about the zone, including the primary name server, admin contact, and sync intervals.

DNS Field Reference

Field	Description
Type	The DNS record type (A, MX, NS, TXT, etc.).
Host	The domain or subdomain the record belongs to.
TTL	Time To Live in seconds — how long the record is cached by resolvers before a fresh lookup is needed.
IP	The IPv4 address the domain resolves to (A record).
Priority	Used in MX records — lower value means higher preference for mail delivery.
Target	The destination hostname for the record (e.g. mail server in MX, alias in CNAME).
Entries	Text content in TXT records, used for SPF, DKIM, or domain verification strings.
MNAME	The primary name server for the domain zone (SOA record).
RNAME	The domain admin's email address, written with a `.` instead of `@` (SOA record).
Serial	A version number incremented on every DNS change; used by secondary name servers to detect updates.
Refresh	How often secondary name servers should check the primary for zone updates (in seconds).
Retry	How long a secondary server waits before retrying a failed zone transfer (in seconds).
Expire	How long a secondary server serves the zone without a successful refresh before considering it invalid.
Min. TTL	The minimum caching time for negative responses (e.g. NXDOMAIN — domain not found).

Frequently Asked Questions

What is a DNS Lookup?

A DNS Lookup queries the Domain Name System to retrieve records associated with a domain — such as its IP address, mail servers, name servers, and verification strings.

Why are my DNS changes not showing up?

DNS changes take time to propagate globally — a process called DNS propagation. Depending on your TTL setting, full propagation can take anywhere from a few minutes to 48 hours. Lowering your TTL before making changes helps speed this up.

What is TTL in DNS records?

TTL (Time To Live) is a value in seconds that tells DNS resolvers how long to cache a record. A TTL of 3600 means the record is cached for 1 hour before a fresh lookup is performed.

How do I fix email delivery issues using DNS Lookup?

Check your MX records to ensure they point to the correct mail server. Also inspect your TXT records to verify that valid SPF, DKIM, and DMARC policies are in place — these directly affect email deliverability and spam filtering.

Is this DNS Lookup tool free?

Yes, completely free. No account or sign-up is required. Simply enter any domain name and instantly retrieve its DNS records.
