Is there any way to know if a particular website in hosted on shared hosting or VPS or dedicated server? can whois help in this in some way?
You may be able to do a reverse dns search and trace it back if they are on a shared server. It will be hard to distinguish between a vps or dedicated server as a vps is really a mini dedicated server. This may be kind of tricky though. May i ask why you need to know? Maybe i can assist you? Send me a private message.
Hostparlor, I don't know how can I check reverse dns which provides me information whether it is on shared hosting or VPS. For example can you tell me for these nameservers NS1.DREAMHOST.COM NS1.ETAXINDIA.NET NS67.DOMAINCONTROL.COM Also please let me know where you are checking this information. I am just trying to know if I will need a VPS in near future, these nameservers are of my competitors sites who are ahead of him, so if they are using VPS then I can get a fair idea if I will need VPS. Thanks for your help.
