All Online Tools by DNS Checker
DNS Lookup
Online nslookup is a web‐based DNS client that queries DNS records for a given domain name.
It allows you to view all the DNS records for a website, providing the same information as command line tools like dig and nslookup, all from the convenience of your web browser.
Note: Nslookup.io does not cache the DNS responses it shows, although the queried DNS servers may return cached data—except for authoritative DNS servers, which always provide the live record set.
How Does Online NSLookup Work?
Using nslookup online is very simple. Enter a domain name in the search bar above and hit “enter.”
This will take you to an overview of DNS records for the specified domain. Behind the scenes,
nslookup.io queries a DNS server for DNS records without caching the results.
You can select from a range of DNS servers on the results page, including popular public DNS servers,
the authoritative DNS server for the given domain, and local DNS servers from around the globe.
By default, only A, AAAA, CNAME, TXT, NS, MX, and SOA records are shown, but additional record types can be selected.
