There are many many services available to "search for domain names", but every one I have found returns results for unregistered domains; whereas I would like to a wildcard search for registered domains.

The purpose of my quest is to identify typosquatting and fake domains, e.g. if my company is example.com then I would like to be able to find exrample.com, exampl.e.com, example.ru etc.

Is there such a service, without enumerating all possibilities and using DNS resolution directly?

TLDR where can I find a list of all registered domain names?

  • Is this SO post asking the same thing as you? Aren't you talking about whois?

  • @Jedi I think he wants a bulk list of similar names, which is hard to do quickly via whois.

  • @AstroDan In the absence free-to-download up-to-date domain lists, I'd say whois is the fastest way to do this. Step 1: Apply mangling to generate list of candidates and Step 2: Perform whois lookup for each domain.

  • TLDR: the list of all registered domain names in all TLDs do not exist. You can get for free the list of all gTLDs published domain names (so you will miss some registered but not published) but for ccTLD it will be extremely difficult, as many registries are against it, to get the list of all registered domain names. Since you do not specify the TLDs you are interested in... Commented Apr 23, 2018 at 1:00

You can also search through http://www.namedroppers.com/. I had not personally used this before but a quick test showed that it does find adjacent domains fairly well. It looks like the online search is free but you have to pay to download the list.

  • This is neat, though it doesn't seem to find nearby domains, it simply finds all domains where the keyword is a substring.

    @jedi You can break up the search a bit more then that see namedroppers.com/uses.html. But you are right it is limited, but it is easy and fast

  • This is a very good resource. This is basically exactly what Anonymous is looking for. Commented Jul 21, 2016 at 20:27

I have done similar analysis in the past by downloading WHOIS datasets, for instance from here.

The dataset has many useful fields including the domain name, the registrant information (name/address/ph). The dataset also spans multiple major TLDs like com,org,net,info,mobi,etc. Note that it is not free, but also not expensive from a product development standpoint.
