I've noticed a handful of SEO hosts selling Class A IP packages, usually for about twice the price of Class C IP packages.

Do you guys think this is worth the price..is there really an additional benefit to separate class A IPs?
 


I don't think there's any sense into it.

I just spread my High PR Domain over 4 Different SEO Hosts and I get plenty of different Class A and Class B ips :)
 
God I hate SEO people when they try to use tech terms and have no fucking clue what they mean.
 
To be clear, I do understand the IP terminology, I really just want to know if there is any additional benefit from changing the A class address range that you do not receive from merely unique C class address range.

When someone refers to Class A or Class C they're referring to networking terminology that has long since passed. Today we use cidr notation, because in the the past the longest subnet you could get was 255.255.255.0 aka a Class C. The shortest you could get was 255.0.0.0 aka a Class A in cidr you would see them as /8 (Class A) or /24 (Class C).

For some reason the SEO world has deiced it was a great a idea to start using antiqued terminology to describe their services. When they say we'll give you different class C addresses what they really mean is we'll give you IPs on different /24 subnets. The same is true for Class A addresses.

Yes, it upsets me more than it probably should.

I've found that C-Class on your own C-Block works best for SEO in the long run ;)

YO DAWG I HEARD YOU LIKE SUBNETS IN YOUR SUBNETS SO HERES A /24 IN YOUR /24.

what you said sounds completely fucking retarded to anyone who actually knows wtf those terms mean.

The only conf I goto is ASW mainly because I'm a cheap ass. If I go any where my whole family goes and I hate the bill that comes with it.

Well there are rumours that if you want to build a High PR Blog network you should build them on different Class C IPs instead of different Class D IPs in the same network.
So people say you should build your sites on:
212.112.203.156
212.112.94.194
212.112.85.123

Instead of
212.112.203.159
212.112.203.94
212.112.203.75
Atleast thats what most SEO "Gurus" say, and I've talked with a few people that high PR networks and they say it looks more natural if your High PR links don't come from the same class C, becouse if they are on the same class C it usually means that they are hosted on the same Host/Server so its easier for Google to determine you are trying to manipulate the search engine results and that Google might not count all of your Links or give them less weight.

I did some googling about the terminology before posting, amazing that I didn't see anyone else making the correction about cidr.

But it still boils down to if two ips from different "class a" subnets would look less related than two from different "class c". Even if that's incorrect terminology. Is there a value to the presumably more diverse looking ip range?

Class D is actually a multicast address...

I guess that makes sense. If both sites are on different /8 subnets it would be logical to believe they aren't related I guess.

BTW I'm a mailer not an SEO person.
 
Class A networks are SE4-level technology, and won't help much unless you've already ninja optimized your meta tags. It's only for people who are at the top of being #1, like expert article marketers who can make 22" linkwheels with spinners.
