I would like to know if Linode has any special conditions/requirements for providing additional IP addresses.

Are the following reasons acceptable for Linode to provide an additional IP?

• Additional IP for a HTTPS website
• Separate IP for hosting a client's non-SSL website
• Separate IP for setting up a TOR relay
• Separate IP for CPanel's interface

I'm asking this because Rackspace provides them only for SSL and that too after proving that you have a SSL cert signed by a valid CA.

We allow additional IPv4 addresses to be purchased only for the first reason (HTTPS), we require verification after-the-fact that you've installed an SSL cert, and I recommend you use SNI where possible rather than using multiple IPs.

Maybe you should mention this on your documentation as it could be a deal breaker for some people.

What does one do if they want to run multiple web servers on a single VM?

Set up Nginx or HAProxy or whatever as a reverse proxy in front of everything else.

Or use IPv6.

Last I checked you can get one additional IP for ip failover.

4. Don't hide details i.e. your domain, it just makes things harder
5. Be polite or you'll be eaten by a grue

That would require creating an additional VM to provide justification.

Do you mean web sites or web servers? We run quite a few sites on each of our Linodes (unless a client specifies they want a VPS all to themselves). If you want multiple web servers then mnordhoff hit the nail on the head.

I meant web servers like Apache and Nginx. Yes I could use a reverse proxy like HAProxy but that complicates things when a control panel (like CPanel) is used.

@akerl: Is there a limit on the maximum number of IP addresses that can be assigned to a single VM?

Hi there,

Linodes can have up to 25 IPs with justification, not including private IPs or IPv6.
