DNSLT is a tool to lookup whois information of a domain, IP or ASN. It is built for people and anyone can use it for free.

Whois is a set of data which contains ownership and other information of a domain name, IP or ASN.

DNSLT use a cache data for 30 minutes. That means you will the same whois data for the next 30 minutes once you searched a whois data. After 30 minutes, you will see a reload button right side of the Domain Info section. Click on it, the data will be updated.

It is because you have entered data in wrong format. For domain name, you need to enter the full domain name, example: dnslt.com. For IP, you need to enter the full IP address, example: 103.148.14.21 or 2001:DF2:B780::1. For ASN enter the full autonomous system number with prefix “AS.” Example: AS140068.
