I have found a hosting plan that is offering competitive prices for different IPs. Yet they mention that they are D Class IP addresses. Can anybody explain if this would be a good deal (since I don't know the difference between C Class and D Class IPs?) Thank you... ps: I am aware of the different rDNS requirements for SEO along with different IPs. I just don't know if different D Class or C Class IPs will make any difference as far as the SEO goes.
