Firstly,
never have 3 redbulls one after the other... I've warned you.

Secondly, (and the reason for this thread)
I have VPS hosting with about 10 websites. At the moment, one could do a Reverse IP lookup on one of my domains and discover all my other sites.

This is a huge security / SEO problem for me for the following reasons:

1. Competitors will see all my websites. The nature of my business is paramount of keeping sites away from competition.

2. Website that are all on the one VPS that have outbound links to one another is (so I've heard) no good for search engine weight. Or in other words, search engines take into account the hosting IP address for links.

So what to do in this situation?

- Do you buy more IP addresses, and have each website on a different IP?

- Get rid of the VPS and use shared hosting for each site?

...What do those Internet Marketers do when they have 50+ sites that they need to keep private from the competition?

Cheers
