Firstly you need to know what blocks make up an IP.  An IP is split up into different sections as follows:

AAA.BBB.CCC.DDD

The C Block typical denotes a neighbourhood of IP addresses.  It is unnatural to get only links from the same C block, as links typically come from different places.  Of course, a few links from the same neighbourhood is ok, but if you had 90% of links coming from the same place then it is probably indicative  that all your links are coming from the same place.

Here is what Matt Cuts had to say about it: http://www.youtube.com/watch?v=AsSwqo16C8s

In answer to your question, you probably don't need to worry at all about C Blocks.  If you are getting links in a white hat way, your links will naturally come from different places, and hence most likely be on different C Blocks.
