Does Dynadot keep a domain portfolio?
No, Dynadot does not and has never kept a domain portfolio.
In addition to dynadot.com, we also own additional domains that make sense for us to own as a business. This includes misspellings of dynadot such as the common typo "dyandot.com" and dynadot itself on other top-level domain extensions such as dynadot.net and dynadot.domains. Most of these domains are simply being forwarded back to our main website.
You may notice Dynadot's contact information show up in the Whois of many domains. This is because the domain is registered with us and the owner has chose to use our domain privacy service, which replaces their contact information with ours. If you are interested in getting in touch with the owner of that domain, you can send your message to firstname.lastname@example.org and we will forward it to the owner for you.
