Hi

I'm trying to setup 5 autoblogs, each with it's unique C Class ip. I know an ip consist of 4 parts AAA.BBB.CCC.DDD. I've heard from backlink Index Express that the number in the C class element of the ip must have a value between 192 and 223.

I've created one autoblog now, but want to verify that the ip is C class ip. I have contacted hostgator SEO Hosting support and they tells me that it's correct. But contacted support for Backlink Index Express (the autoblog guide I follow), and they say the ip is not correct, it should be a number between 192 - 223

My first blog in this blog network has the IP xxx.xxx.236.xxx.

I've checked that with Hostgator SEO Hosting each blog will have a unique C class number.

So I wonder what is correct here?

    I may be wrong, but I think you are looking at the wrong number.
    Look at the first number.

    Class goes by the first number.

    Incidentally, amazon is class a, warrior forum is class b.

    I won't even mention what you are trying to do with class c and
    5 autoblogs.

      Huh?:rolleyes:

      The OP is right, an IP address has 4 Class numbers, in the format: AAA:BBB:CCC : DDD.

      If 2 IP addresses are said to be "C-Class Unique", that means that they are have different A-Class numbers, B-Class numbers OR C-class numbers.

      Not sure what you mean by amazon is class a and warrior forum is class b

      WF's IP is: 174.37.60.234

      The a-class number is 174
      The b-class number is 37
      The c-class number is 60
      The d-class number is 234

      So,
      174.37.62.234
      174.38.60.234
      175.37.60.234

      Would all be C-class unique to WF.

      174.37.60.222

      Would not be C-class unique to WF (it is unique at the D-class level)

    I'm quite confused. That just isn't true. For instance, the IP of WF is: 174.37.60.234. Not sure who at BIE/DataSystemsPlus said that, but i'm sure it isn't Carl.

    ?? All IP numbers have a C-Class IP.

    OK, I think you are even confusing yourself now. The IP address isn't relevant to the actual installation or setup of BIE. It is only relevant for your own purposes..which it seems to be to check to make sure that they are C-class unique.

    You don't need to know your IP addresses to setup BIE. BIE can be installed on any host, and then you simply tell BIE (through the uploaded files for that install) which WP blogs to post to, by giving it the WP web address and login info. No IP info is needed.

    Just set up your hosting for your autoblogs, install the WPs, and then use either an IP lookup or a firefox plugin like SEO Quake to check the IPs to verify they are unique on the C-class level. Note that if IPs are unique on the A-Class or B-Class level, then even if they have the same C-Class numbers, the domains are C-Class unique. It is the like having a street address of (15122) in Denver or Monte Carlo. the street address might be the same, but the city and country are different. So, that is all Good.

    Then, just install BIE as outlined in their instructions. You shouldn't have to know your IPs for that.

    according to hostgator, if each blog as it's own c number, then they are hosted on unique c class ip. Example xxx.xxx.236.xxx and xxx.xxx.198.xxx will be on different c classes.

    I understand what you write, that is exactly what the BIE guide tells. But I hostgator support say C class ip is something different. I wonder how important this is for getting the blogs indexed

      They are correct, with one cavea: if they are unique on the a-class or b-class levels, they will also be considered "c-class unique.". But, with seohosting.com i'm pretty sure they are all on the same a/b-class IPs, so for this purpose that isn't relevant.

      Don't worry about it. Just double check that the IPs are c-class unique by checking their IPs, and install BIE as instructed and you will be good to go.

        Okay. Maybe I'm confused.

        Aren't classes done by the first number?
        First one for class a is up to 127, class b from there on up to 191, and
        so on?

        If we take your explanation, I see a 60 in the slot the OP is referring to.
        That can be anything up to 255 for any class.

        Maybe I'm just dumb today, but I was under the assumption that class
        refers to the first numbers in the ip address. That is, the first octect
        is the number you check. Not the rest.

        Warriorforum is 174.37.60.234, 174 is between 127 and 191, hence
        class b. Explain how that ip is class c? That third octect can be anywhere
        between 0 and 255, right, no matter what class? 60 is meaningless as
        far as class goes. If you can give me the skinny on class that I am
        mixed up on, let er rip! I'm all ears.

        WF is not on a unique server. louisianabeagle.com is just one of many on it.

          I think the confusion is that it appears there are two uses of the term "class a" (just looked it up:rolleyes. When IP addresses where created, they did in fact refer to Class a, b and c, as "Historical classful network architecture" (Wikipedia terms).

          However, each IP address itself is also broken down into 4 terms, each with a class letter (a through d). Whenever someone says "C-class unique IPs", or "I have domains spread across different a-class, b-class and c-class IPs", they are referring to the description the OP laid.

    Yes, the meaning of "C" is that it is on third position of your IP address formation.

      Sorry but the subnet is actually controlled by the subnet mask!

      255.255.255.0 is a class C (254 addresses)
      255.255.0.0 is a class B (65534 addresses)
      255.0.0.0 is a class A (16777214 addresses)

      This determines the size of the network OR the number of IP addresses available on that network.

    I think you are looking at the IP "class" too much. Yes "C"s are technically above 192 BUT you can split a class A or class B network into multiple class "C"s.
    I think what's important here is having 5 separate addresses and it sounds that they want you to have each on a separate class "C" subnet. The 1st octet (1st number of IP) is different for each IP. This isn't easy I have 512 IP's with my company and I have 2 class "C" subnets. Most ISP's will give you adjacent IP's. Only the largest will have a big enough network to have enough IP's to span different class "C"s. Not sure why they want this we mail servers on different IP's and the threat is that if one sends a large emailing they would mark the whole IP block as a Spamer, it hasn't happened, they treat each IP separately.
