.LK Domain is the Top Level Domain Name Extention of Sri Lanka. There you can search your LK Domain's availability, expire dates, category type and price. You can simply enter your LK Domain with or without ".LK" part and search. After a few seconds, you will get the results.

Another important thing is you can see all DNS / Nameservers of Registered LK Domains also. So no need to check DNS from another place. More features will be available in the future.

Enjoy!
