You cannot easily find all the domains that point to an IP address. There are a couple reasons for this: 1- You are looking for all forward lookups that return this IP address. There is no way to get this information (you would have to look at every domain). 2- Reverse lookups (using PTR records) do not have to match all forward records. 3- There is no query function that aggregates the data. I think there was an old, obscure query that was eventually removed because the size of the internet made it too slow. see: https://en.wikipedia.org/wiki/Reverse_DNS_lookup you can not make this by your own from 0 to 100! You should use ip-databse or other api services! look at this part on your sample website :
