nameserver sharing ip with a site
| Posted by johnm160, 04-13-2011, 12:09 PM |
| Hi everyone,
I have a question that I have not been able to find the answer to. I have a VPS with 3 ip addresses, one shared and two nameserver ips.
One of my reseller accounts somehow managed to create an account on the ip address of my secondary name server as shown below.
IP1- site1, site2 site3.....ect
IP2 - NS1.site.com
IP3 - NS2.site.com + a random reseller site
Does having a site hosted on the same ip as the nameserver pose any problems?
Thanks for the info
John

| Won't cause any problems; except, that when someone goes to http://ns2.site.com/ you might see the resellers website (depending on your exact setup).

| nop.
although i must add its bad practice to have all your name servers hosted on 1 box.
imho, get a cheapy $15/year vps to run as a dedicated nameserver.

| Yeah I know, IDK why they give you two IPS for nameservers and locate them with no redundancy. I don't really want to do another vps to run a nameserver, I was going to look into offsite dns hosting for the secondary. If i remember correctly there were some places that did it for free or very cheap.
However after a quick search it looks like it is not as cheap as I remember. Where can you get a $15/year vps?

| I guess the thought is if the dns sever goes down the sites went down too since they are all on the same box. So not gonna be reachable even with redundant DNS. LOL

| Correct.
If the web server is down, website is unreachable with active DNS.
Website is also unreachable when web server is up but dns server is down

| It won't post any problem.
You can use your Static IP for web hosting and name server in the same time. They are using the different port number.

| if the server is down, but you have redundant dns, mail to that box will at least be reattempted. if the domain can't be resolved, delivery will bounce.

| It depends what it's for and is it mission critical. I didn't see a problem with this on my non-critical KnownHost VPS with a 99.9% uptime guarantee. And no big deal even if the data center were down for a short period of time due to upgrade or DDOS. I won't lose thousands of dollars in revenue.

| Nowhere if you expect it to be online very much - and for DNS it'd be fairly fundamental to have high-uptime as it'd be used for 50% of your queries !
$15/month for a CPanel-DNS VPS would be about right, or look at a secondary dns system that can automatically AXFR the zones from your server as they change ...

| BuyVM is a great place, they're $15/y and I haven't had any major issues for the time I've been hosting with them (since June 2010). At some point in the future they should be offering a cPanel dnsonly template. The $15/y will need it's memory temporarily increased to handle the install (throw in a ticket), but it should run fine on it afterwards from what I hear.
@othellotech: Haha. Sure...
