I target SEO hosters
I looked to see what is needed and how I can provide that need cheaply and professionally.
Many SEO companies will have many hosting acounts with different hosting providers, so that they can have blog sites and comparison sites all on different IPs. Not just different IPs, but of different networks, so that google and other services see their sites are being owned by different people.
I've taken many ripe blocks and forward an ip from each block to a different dedicated server. This way every machine has many IP addresses on different Class C Networks.
I've then shared these IP, so that my resellers do not have to purchase dedicated IPs to have multiple IPs on different Class C networks.
This allows them to have a single account with me rather than multiple account with others.
Also because these are SEO people, I've beefed my servers to 16GB of RAM etc to make sure they are fast!!
I'm a little more expensive than the average host, but that way I can afford to have fewer users per server!
So my target audience is Fast Responce SEO aware people
