Why more than one IP ?

Hi, noob question here, but I'm wondering what's the deal with having more than one ip when purchasing your vps? I imagine something useful could be done with another ip as providers charge for it.. but can't think of specific usecases because maybe I just use my vps for simple things.. does it have to do with load-balancing? or as using the vps as proxy?

LowendTalk I invoke your wisdom :-)

    You really don't need a dedicated IP for Minecraft or most any multiplayer pc game, its just more convenient.

    SSL, non-redundant cpanel nameservers, spam, "seo", usually 1 is good, or 2 if you want to run some stuff on the other one for security reasons. I don't get why you'd need more then 2 IPs for personal use really but I'm sure minecraft kiddies dont mind paying extra for the dedicated ip when renting a server.

    No, but ports confuse some players so to have a dedicated IP is a plus.

  • If running websites i always have 1 ip listen for http /s only and the other one listen for other traffic. Ftp ssh web panels etc. And just connect to them by ip targeted attacks are less likely to happen then.

    How is useful more than one ip for SSL ?

  • @MrLabradoodle said: No, but ports confuse some players so to have a dedicated IP is a plus.

    Minecraft supports SRV records now so there is no need for dedicated IPs anymore.

    There is. What if the user wants Votifier, DynMap etc. which requires their own port?

  • Vanity hosts, i.e. for IRC. Although i can imagine most people would use ipv6 for this nowadays.

  • @SimpleNode said: What if the user wants Votifier, DynMap etc. which requires their own port?

    They can get their own port. I'm sure they don't have a hardcoded standard port.

  • @gsrdgrdghd said: They can get their own port. I'm sure they don't have a hardcoded standard port.

    Correct, however some server ranking websites do not allow you to use a custom votifier port, and some less known plugins do not allow you to change ports.

    one IP management and one public services.
    Not that I recommend it, but saw in practice. And, to quote someone's quoted reason for another IP: "if my VPS crash I can use the other IP".

    No, it doesn't, see http://en.wikipedia.org/wiki/Server_Name_Indication

    If you're still using IE6 you've got worse things to worry about :P

  • @kuro it's not what we use... it's what the customer uses.

  • "Our website shows up in IE fine. So it's not my problem. Switch to IE, sir."

    No really, SSL desn't require dedicated IPs.

    who told you that? it dose require a dedicated IP unless you are installing it on the hostname

    No, If you are using WHM/CPanel can be installed, just use nobody instead of account username.

    Thats wrong, every major browser supports SNI nowadays.

    I'm sorry, what?

    The cluelessness just flows off of him in waves. I'm going to have to buy a dosimeter to make sure I'm not soaking up dangerous levels of radiation.

  • if you are using Cpanel/WHM , you dont need a dedicated IP to install SSL on the hostname, that is what i meant

    The combination of Windows XP + IE will get you disastrous result. Of course, unless you have a way to force all the corporate customers to fix it.

  • for security reason. listen only to ip that you don't use for web server, mail server etc. and also for vhost :p lol

    SNI doesn't work on any version of Internet Explorer on Windows XP. That's a significant proportion of the browsers in use today.

    I remember some people on the internet claimed that having multiple ip addresses that pointed to a website caused you to get increased pageranks. I am not sure how true this is and I suspect its not true at all but thought I would mention it. As for a logical reason I can think of, perhaps you want to do 2 different services on the same port, so you would be able to bind a specific service to one ip / port and another service to another ip / same port...

  • Google penalizes you for having the same content available from different URLs. So using two separate IPs isn't going to help your pagerank at all.
