What impact does multiple links from the same c-block have on SEO?

Recently there's been a move made in my company to only allow backlinks from websites on different c-block IP addresses. The most links we have from one c-block is 15. There is a wide variety of other IP addresses linking to our site as well. My question is - do we need to be so restrictive with using websites from the same c-block as long as the neighbourhood is good and we're not linking sites with full identical IPs (matching d-block as well)?

If you take links from c class ip sites which are handled from the same company/owner, then it is harmful. if owner/company is different, then no problem.

We're not even talking identical IPs in this situation, we're talking matching c-block but unique IP. Would your answer still be the same?

Thanks James, I just wanted to clarify as it was not clear you were making that distinction in your initial answer.
