Customising/redirecting tumblr address using streamline.net domain with no A-record
I am such an internet idiot, I have no idea what I'm doing when it comes to html...
Basically I have a tumblr blog, which has a free tumblr url like suchandsuch.tumblr.com. Now, I own my own domain with streamline.net, like suchandsuch.co.uk, and I would really like this to redirect to my tumblr blog, but with that url and not the tumblr one. I know I'm probably not making that sense but stick with me...
Tumblr say that to customise my tumblr url I should redirect the A-record of my domain to their IP address. I contacted streamline after having no luck finding the a-record and they say they don't support a-records. Is there any way for me to re-direct the IP address without altering the a-record? Does anyone know what the streamline equivalent of the a-record is?
I've inserted a java script that redirects the window to the tumblr blog, but it's not the same thing because, as I say, I want the .co.uk address to BE the tumblr blog not just redirect...
Any help would be great - thanks. Especially if it is in words I can understand being a technophobe. ;)
