Looks like a new scam is in town. This one is trying to trick you into send them lots of money to renew your domain. They are able to get your domain registration information from the WHOIS database.
This is a scam and should be ignored at all costs.
Who are they?
The letter comes from a New Jersey address and their official name is Internet Domain Name Services Inc. Their website is listed on the letter as www.idns.ae. The AE top-level domain is for the United Arab Emirates. Previous letters had a different web address registered in St. Helena, Ascension, and Tristan da Cunha. They could’ve registered that unusual domain to avoid consumer protection laws in the United States.
The company uses a Jersey City New Jersey business address. According to Google maps, this address looks like it is a UPS store.
