If you have a web host, chances are it's already running on a fixed IP address, or at least has some provision for mapping a fixed URL to the server's IP address. I think we'd have to know a lot more about the host and the network it's in to even guess at a solution.
Is Dynamic DNS reliable?
Hi,
I'd like to get readers' views on whether Dynamic DNS is effective and reliable enough to use on a commercial scale?
Basically I'm developing a portal for a non-profit organization which is on a budget. They want to be able to send and receive mobile phone SMS to/from their volunteers. The portal is being hosted on a shared web host, so I can't attach my SMS gateway to the server. So I'm thinking of plugging the gateway into the server in my client's office and connecting to it using Dynamic DNS.
I expect that there will be up to 2000 SMSs sent/received per month and the service must be up 24/7 without interruption (or at least 99% of the time).
Is Dynamic DNS feasible or should I not even be thinking of going this route?
Thanks for the advice.

Sorry for not being clear. The issue is not the shared web host, but the ISP for my customer's office.
The office subscribes to a dynamic IP ADSL Internet connection. As you know, the IP address changes everytime the router restarts or the connection gets re-connected. I want to host a website (an SMS gateway rather) on the office server. The way I found I could do it is using Dynamic DNS, which tracks the changes in the IP address and updates it on a external redirection server.
My question is: How reliable is Dynamic DNS? In principle it seems sound, and I've tried it out on my own machine and it seems to work. But do any companies use this for sites that get several thousand hits a month?
Thanks.

I have been running 3 or 4 websites from my house for the past 2 or 3 years now. I use www.dyndns.com. it is affordable and also my ip doesn't change a whole lot. generally routers have a setting for dynamic dns.
I have had no issues with www.dyndns.org keeping up with my IP address. I don't see this as a significant issue.
FWIW, I'd run the DynDNS client on the server, the router features that I've used have been somewhat unreliable.

john tell me more about the dyndns client on a server, please.
You can run the DynDNS updater on any machine in your system, and it'll keep the IP address updated. Since my main machine that I use every day is on all the time, I have the updater running there.
I've had several routers that had DynDNS capability, but they obviously didn't handle it correctly, because after the 30 day update maximum, I'd get an email from DynDNS that my account was going to expire because it wasn't being updated. I decided that wasn't the way to go...

I use no-ip at http://no-ip.com for this.
The thing is, no matter how good it is, it won't have 100% uptime. There'll always be that time in between updating, and the client machines refreshing their DNS cache where things won't work.

Thanks all for your answers!
I think you're overstating the case for 99.9% of the broadband accounts that exist. The IP address doesn't change all that often, mine stays the same for months at a time.I use no-ip at http://no-ip.com for this.

Well mine changed about once a week, probably because I had a flaky connection.
Yes Dynamic DNS is reliable. Only instance where I've met failure is when IP its passed on to someone else (dearly needed) and the IP has been through the rounds of a troubled person (blocked on sites etc). When this occurs, no connection can occur repeatedly. Other than that I've had no problem running DynDNS multiple times.
And this had nothing to do with the reliability of the DynDNS service. I have mine check every 5 minutes, and it's worked for several years that way. Even with the IP address changing every week, this would be a very small window of downtime, try 0.05% as a maximum number.Well mine changed about once a week, probably because I had a flaky connection.
