Not really ... you don't need to worry about IP's so long as the links are legitimate.
HINT: you don't want advertising links to spoil this... that is, links anchored with the phrases you desire ranks for just because you desire the ranks... it defeats the purpose of doing all this editorializing.
So how do you incorporate advertising links (a.k.a. paid links) without appearing like paid links?
