No they don't - in the same way that they're not devalued by just being on the same IP or class C. Google uses a lot of information to determine whether sites are "related". Using the third octet of the IP address isn't a good way for them to do this - Google surely knows about CIDR which made classful addressing obselete in the 90s.

If you want to try to scam Google and have a network of sites linking between each other, then just changing the third octet of the IP isn't enough.

You said that 'class c is meaningless'

That's not true....

Matt Cutts works for google - you believe everything he says?

Class C is a meaningless distinction since the mid 90s when CIDR came out.

Inspecting the third octet of an IP address means absolutely nothing in networking terms, it doesn't "tell" you (or Google) anything useful.

* has nothing to do with the google SERP...

Why do you say that? Google's interest is in making sure that links between sites are legitimate.

If (as you intimate) that one of those tests involves looking at the third octet of the IP on which two websites are hosted on then you're also saying that Google is relying on classful addressing - that is, that websites hosted on different class Cs are on separate networks. This is not the case and hasn't been the case since the mid 90s.

I can't see Google relying on an outdated routing/addressing methodology (that was outdated when Google started) to determine whether sites are related.

The only people I've generally seen talking about class C addresses are low rate SEO companies.

I'm not sure you're getting my point...

I understand your point that you say a bunch of sites all linking together on a bunch of different IPs won't get busted... Of course you have to be tactful.

Different 'class C' hosting ISP's usually have different incoming links with different ISPs that have totally different 2nd or 3rd octets - not just 'class c' addresses - but try to write that in a way a non-tech could understand.

Different hosting companies (as you yourself stated) is one way to put a tick in that box - but a good seo friendly ISP will also provide the same level of disparate IP addresses.

Like Heart internet do..

The first 3 hosting sites I've just picked at random have these addresses:

79.170.40.160
79.170.42.2
79.170.44.118

Again - this works for me as my primary site isn't even hosted at heart - and I don't link between the sites.
