My provider told me that they cannot give us a separate IP address for a separate website. I understand that they could give us one where an existing address absolutely cannot be reused, like if we had a second virtual server, or required SSL.
Having browsed around, it seems that this isn't really up to them, and is imposed "from above", leading me to wonder if this applies to all hosts in the US.
If this is not so, please could you recommend a good webhost with servers in the US which are happy to issue several IP addresses without requiring extra virtual servers?
P.S. I could get a separate virtual server for this, but that seems daft. It doesn't save any IP addresses whatsoever, and only wastes extra electricity in the process...
