Question About Website IP Addresses
 

Anyone know whats the difference between having 10 websites sharing 1 unique IP address on a dedicated server or those same 10 websites each having their own unique IP address on the dedicated server? Which is better?

Are there pros and cons when the same websites share the same IP address or when they each have their own unique IP address?

Thanks

anybody? :)

Makes no difference you're just using more IP's. But unless you're gonna call the sites directly from IP address, there is no use in giving them all seperate ones!

Separate IPs is possibly better for SEs.

you know, thats what my sysadmin keeps telling me, but then why does anyone bother having different IP addresses on their box in the first place? With what you're saying, each dedicated server would just need 1 IP address and be able to host 100's of websites on that IP address. Yet most people with dedicated servers have a unique IP address for each website.

I never have on any of my boxes I've had. All vhosts use that too, basically it's virutal hosting. And it cost's the hosting companies money on the blocks of IP's they buy and if they use one for every single site, they run out quick. All the boxes I deal with use one IP address for all sites :)

I don't see how this would efect SE results!

On my dedicated boxes, I have 5 IP's .

2 are used for the nameservers ( dns), the remaining 3 to allocate to sites.
The only reason I know to give a unique IP to one site is to prevent it from being banned ( spam. DDOS, etc...) tough the host will ban a whole block.

To get supplementary IP's, you have to justify them.

Hmm, I see.

It just occurred to me, if you're hosted on a virtual server, and someone on that box is spamming and gets the IP address on the box blacklisted, you'd be fucked.

But I think all virtual servers have had spam problems, and yet not all the sites on their boxes become blacklisted, so who knows. :)

some se's wont list you if you do not have unique ips assigned to your domains

Some not-so-good spiders choke on virtual hosting. For automatic spam detection it's also blazingly obvious when you have a bunch of crosslinked domains all on one IP (and indeed a densely crosslinked subnet on a bunch of IPs in the same class c). Some SEs also ban by IP, and if you are sharing an IP with others then you can potentially be penalized by the actions of another site owner on the same IP (or even the same class c in extreme cases). Google claims that they don't penalize by IP but IMHO better safe than sorry.

It is best not to host multiple sites on 1 ip unless you don't care that anyone can see all the domains you're running off that box. This information could be particularily useful to competitors.

In fact, you can sign up for a new box, get five IP, and realize that they are banned or listed in the SPEW list. I had a new box banned at Easypic tough I never was banned or even submitted with that box...

Spammers use a box for a month or less , than move on to another ISP, and so on, leaving a trail of IP's banned or in SPEW list.

:2 cents:

I dont see any way to contact you. Do you think you can shoot me an email at somecreep1 [at] yahoo [dot] com or list your ICQ if you have one?
