As László Monda wrote, what you are looking for is a captive portal, such as Chillispot (et al.) Such applications are really dedicated to providing a web page where visitors must enter a login and a password to continue surfing.

You can use dnsmasq to send visitors to the same IP address. Unlike a captive portal it can't be dynamic as you'd have to stop the redirection as soon as users are identified, which can't be done easily with dnsmasq and most probably not on a per-user basis. Moreover you'd permanently have every network packet sent to the same IP address, not just web traffic.

Hope this helps,
Vince C.
