Setting up your IP's

Izzmo · 03-21-2008, 12:26 PM

So, I have 10 IP's currently for my server.

I have 2 hooked up to my 2 nameservers.
I have 1 for the main shared IP and hostname.
The rest are unused

What would be a good way to use all of these?

I called up a guy from my datacenter, and he said he would use a couple for his main hosting website, so even if his clients sites were down, there was a good possibility his main one was still live. How would I go about doing this?

Now, I did try setting up my site to go to another IP, it worked. I got an error later saying that my hostname IP was not the same, so I reset the A Name in the DNS settings to coinside, which I think fixed the problem. So, how would you setup 2 IP's to your main site? Or is this even worth it?

Do you have a root access?

Considering I'm posting in the dedicated server section, yes

Which os / control panel are you using? In most control panels, changing the IP is just too easy. But having dedicated Ip doesnt guarantee you better uptiime!

Yes, it is easy. But I'm changing the IP on my main website. I can do it, but then it starts showing my default cPanel page (the green one... Welcome to Apache! or w/e) instead of my site.

This is.. if I try to add another IP to the site.

I can get 1 dedicated IP hooked up to my site fine, it's just 2 that I can't get working. Is this possible to do? And.. is it even worth it?

I think it's possible, all depends on your purposes.

And, how would I achieve this?

Not sure why you feel the need to??

Well, I don't really see any logic in that statement. The only potential reason I can see that giving any better resiliency is in the event of routing/network problems. Any other problem which comes to mind would affect the whole server...

However, with routing/network problems it's most likely that the connection to the server will die (e.g. if the switches/routers in the DC have problems) or if it's an external routing issue of some kind a whole block of IPs will be affected - I guess including all 10 of yours at once.

I think I answered that

This ought to be possible to do, but I don't think cPanel (or any other panel) will let you do this via the interface because - as above - there's not really any point.

I guess that you could just configure Apache (i.e. by manually editing config. files) to serve the same site etc. for 2 IPs, but I can't say that I've ever tried it

If you want to have your website online in the event of problems with your customers websites then you should look to host your own site on a separate server. Generally this doesn't look so good if your site is in a completely different location (i.e. a different datacentre / country) so host the main website on your own server with your customers, then host a support/customer portal micro-site elsewhere.

We have two hosting locations on completely separate networks and our support system is located in a third location. This seems to work well, and our customers like the reassurance this gives. Depending on your needs and budget you could use anything: a solid shared hosting plan, a VPS, or a full dedicated server.

You can do more complicated things with redundancy and mirroring etc. (at a price!) - but if your hosting is that unreliable then maybe you should stop charging people for the service?

Thanks for the detailed reply Damien!

That answered all my questions. Prior to reading your comment, I already gave up on the 2 IP idea for the reasons you stated.

Since you seem to be knowledgeable in the subject, is there any way to host a single website on your Apache/WHM box with a different port?

I want all my clients to be on :80 like normal, but would like a certain site to be on a different port, for security reasons.

I know this is very easy to do with IIS.
