DNS Lookup Tool
Instantly lookup A, AAAA, MX, NS, TXT, CNAME, and other DNS records for any domain.
What is DNS Lookup?
DNS (Domain Name System) Lookup is the process of retrieving records associated with a domain name. When you perform a DNS lookup, you're asking the internet’s “phone book” to give you specific details about how a domain functions — including where it's hosted, where emails go, and other configurations.
How Is This Data Fetched?
This tool queries global DNS servers using standard protocols. When you enter a domain (like blinkai.co), it sends a request to a recursive DNS resolver, which contacts authoritative servers to retrieve all available public records such as A, MX, TXT, NS, SOA, etc. This process is real-time and reflects the current live configuration of the domain.
Explanation of Each Record Type
- A Record: Maps a domain name to an IPv4 address. It tells browsers where to go (the server's IP).
- MX Record: Specifies the mail servers responsible for receiving emails for the domain. Includes priority levels.
- NS Record: Indicates the name servers that manage the DNS zone for the domain.
- TXT Record: Contains textual information. Commonly used for domain verification and SPF/DKIM authentication.
- SOA Record: Start of Authority record. Stores important info like admin contact, refresh interval, and serial numbers for syncing DNS changes.
Field Descriptions
| Field | Description |
|---|---|
| Type | The type of DNS record (A, MX, NS, etc.). |
| Host | The domain or subdomain associated with the record. |
| TTL | Time To Live, in seconds — how long the record is cached before refreshing. |
| IP | The IPv4 address linked to the domain (A record). |
| Priority | Used in MX records — lower value = higher priority for mail delivery. |
| Target | The destination server for the record (e.g., mail server). |
| Entries | Text values in TXT records, often for verification or SPF policies. |
| MNAME | The primary name server for the domain (in SOA). |
| RNAME | Email of domain admin (written with . instead of @). |
| Serial | Incremented when DNS changes; used by secondary servers to sync. |
| Refresh | How often secondaries should check for updates from the master. |
| Retry | How long to wait before retrying a failed zone transfer. |
| Expire | When secondaries should stop responding if the master can't be reached. |
| Min. TTL | The minimum cache time for negative responses. |
