Host Header Manipulation

Does anyone know if I can alter the hostheaders for the site within ASP.NET? I dont want to waste hours to find out I cant...

Well there are certain settings you can change in IIS. What precisely to you want to change?

Sorry I posted that message with v.limited understanding of what I was doing. I need to manipulate the domain A records through asp.net but my hosting company can provide this for me so its sorted :-)

Thanks anyway
