Why do you need IPs?

Well, with lots of IPs being given out by a few hosts for free, this question begs to be asked. Why do you need lots of IPs?

    I require 2 IPs on some of VMs because I use them to host web-content and an OpenVPN server. I run each on separate IPs so that when connecting to the web-content via the VPN, the traffic is still tunnelled.

    Most get them for VPN/spam/irc from what I have seen.

    VPN? Why do you need multiple IPs for a VPN, unless you're doing something bad...

    Haha, that's great.

    VPN services, spam and hosting websites on dedicated IPs. There are more but I can't think.

    Because Buyvm gave me then? Why not!

  • I have openvz containers for mail server, web and mysql, game servers and development so that if I muck anything up the rest of my services will still function normally!

    Just to have as many as possible so when they run out and the price rises... profit.

    I, uhh, I don't think it works that way for the end user... :P

    What a great reason.

  • rds100rds100 Member

    @Steven_F no, it's that way for the providers :) This is the reason for the offers with many free IPs.

    @rds100 explained why providers offer much IPs. The reason the end user gets them is cause they are free or dirt cheap. TBH, I rarely use more than 1 IP per virtual server, however if they are giving 30 for free, why not?

    Backup servers wouldn't even need any IPv4 addresses (NATed only), because it simply doesn't matter if you rsync your stuff to port :22 or :25901. Hey doesn't that sound like a new kind of offer? Some OVZ container with auto 5 nat port assignment, auto ssh setup and a lot of space (i know that exists, but often this is at the very very low end of things like LES).

    @Nick_A, actually i am really interested if a ramnode box can be cheaper if you don't want any IPv4?

  • Usually just two, for hosting sites.

    I'm curious from a user's end, not why a provider might.

    I feel after some thinking and configuring you can get the behavior you want with just a single IP.

    Not just IPs, but VPSes and servers in general. Oh, but of course personally I don't have this problem. And it's not like all my machines are named after anime girls, or anything of that kind. Absolutely, absolutely not.

    Yeh you can if you want to be fiddling about with it.

    Save IPs, waste time! Fiddle about! :P

  • @Steven_F said: Well, with lots of IPs being given out by a few hosts for free, this question begs to be asked. Why do you need lots of IPs?

    (1) On any VM's to host multiple domains with SSL,
    (2) On KVM's with virtualization setup, using additional IP's to run OpenVZ or other containers.

    So I've heard, but havn't tried installing one like that yet. BTW, is this true for EV SSL's, too?

    AFAIK yes, not entirely sure tho. Might wanna do a quick search or wait for someone to confirm / deny this :)

  • xDutchy said: SSL doesn't require a dedicated IP anymore

    HTTPS does not require a dedicated IP. However, there are other TLS (SSL) encrypted applications that do - any application that does not use the HTTP protocol (and does not uses the hostname header). For example, IMAP, Exchange, SMTP, XMPP, etc.

    Plus here is a little tidbit I have just came across while playing with Nginx under Virtualmin:

    Nginx as configured by Virtualmin lacks some features of Apache, such as :

    • Only one virtual server can have SSL enabled per IP address, even if a wildcard or UCC certificate would potentially allow multiple SSL sites to share the same IP.

    Does anyone here know if this is Virtualmin-specific only, or equally true for any server running Nginx (without Virtualmin on the box)?

    People keep saying this, but other people keep using Win XP.

    And with IE, especially in the corporate world.

    Pretty certain XMPP does not require an IP per domain either.
