    Why use several IPs?

    I know there has to be a simple answer =)

    I've been hosting all my web pages from a dedicated server for years now (you'd think I'd learn more than I do now after that long!), but I've never needed more than 1 IP per server.

    What are some reasons you guys need extra IPs? Maybe I'm missing out on a big secret! No, but really...please explain it so that even I can understand.

    So basically....if one IP is blacklisted, you want another. I understand that - but why would you need another IP for anonymous FTP? And why would you need another IP for SSL?

    I've never really needed either SSL or anon FTP, but I don't see why you would need another IP for either of those.

    Also...any other reasons?

    ok say you hosted 2 domains on the same ip and you were going to try to give them both anon ftp well they would be sharing the same one since if a person logged in it would be logging into that ip of the anon ftp where as if you have your own dedicated ip for just your site it will be able to have anon ftp

    sort of hard to understand but without it you can't have your own anon ftp or ssl cert

    for specific scripting reasons... some of the larger resellers of mine... i dedicate an entire IP to them... just so they can have their own separate apache and all with custom headers and apache modules/etc... but that involves recompiling apache independantly for each of the resellers... heh... in addition, the apache runs under their own username (as the reseller) instead of nobody... so the reseller's clients can't mess with data from other resellers via PHP/etc... heh... i m trying to figure out how to do some sorta chroot() easily... heh... by this point... it starts looking a lot like a VPS... heh

    You can't use name based hosting for either of these services because the client does not send the host name when connecting (which it does for regular HTTP - or at least for HTTP/1.1).

    For anonymous FTP, the host name is simply not present in any part of the protocol. For HTTPS, the reason is very technical but basically the host name can't be sent until it's too late to do so.

    Some search engines favour dedicated IPs.

    That has been disproved many many times in these and other forums about search engines favouring sites with their own IP.

    I stand corrected
    However, you should try telling that to the search engine specialist company we host.

    lol, perhaps their not so "specialist"

    The only disadvantage regarding search engines is that you may be on a shared IP that is blocked for spamming that engine, then again you might get a dedicated IP that was also blacklisted due to spamming.. but at least that can be changed easily

    nah... i don't have many clients... might as well take care of the few that i do have... hehe...

    as far as the search engine stuff... a friend of mine that does search engine promotion (and is very wealthy because of it)... well... he says it doesn't matter anymore... before the spider scripts used to not be HTTP/1.1 compliant, now they are... so... if that helps any...
