Who is DomainSpot and why do I see it as my registrar when looking up my domain?

In this article:

You may have looked up your domain name via a public whois search and found that the registrar information shows DomainSpot LLC instead of TierraNet. Back in 2021, TierraNet was acquired by DomainSpot which meant we also had to update the registrar information for all TierraNet registered domains.  If you're unsure whether your domain is registered through our services, we welcome you to look up your domain using our WhoIs Lookup Tool.
