Summary

Description
Dynamic internet address publishing:

So you've paid for an ADSL/DSL/Cable connection, fast Internet, always on BUT - the IP address they provide is dynamic. Great! You get high-speed internet access but every time the line drops, you get a new internet address.

dynamicIP allows you to use your dynamic service like a static service. dynamicIP runs on your gateway machine or device connected to an ADSL/DSL/Cable modem or router:

  • Keeping your connection up by frequently accessing the internet
  • Writing your leased address to an upload page
  • Publishing the upload page to your hosted site
  • Optionally published your IP address to SMTP email and www.DynDNS.org

Why use dynamicIP

I pay BT for an ADSL line but I chose not to pay extra for the business service (an extra £100+ a year). Unfortunately, the basic service only provides me with a dynamic address. But BT keep dropping the service so, even if I keep my server on, the line drops and I get a new address on average, every 4 days. So what can I do...

dynamicIP provides the solution. Running dynamicIP on my server machine, dynamicIP ensures that my leased address is kept alive every minute of the day. But the line can still be pulled by my service provider and anyway, keeping the address up is no good if I don't know what it is...

dynamicIP also gets hold of the dynamic address and published this address. You provide a template web page and a place to publish (your web site, FTP server, free web space, etc). Every 5 minutes (or as frequently as you desire), dynamicIP picks up you leased address, writes this to the template file and via FTP, uploads the template file. So no matter where you are, you can link to your home host - even if your service provider pulls the connection.

Using dynamicIP

dynamicIP is simple to use task bar application. After installation, you will have to set up dynamicIP - this is done the first time you run the application. On first running you are presented with the program's main screen:

dynamicIP has five tabs on the main screen:

Taskbar Application

Once running, dynamicIP can be hidden from view. Notice the dynamicIP icon in your task bar:

  • The icon changes to reflect the running state of dynamicIP:
    • Red Icon when an error is detected.
    • Yellow icon when loading and unloading
    • Blue icon when running
  • Double click this icon and dynamicIP will restore its window.
  • Right click this icon to display the icon menu for:
    • Showing the main window and
    • Exiting dynamicIP

Once you have set up the initial parameters, click the 'Start' button to start the polling and upload process. Every refresh period (initially this is every 5 minutes but you can change this from the menu), dynamicIP updates your template file with the current leased address and uploads the template file to your FTP site. Every 10 seconds, dynamicIP polls the internet for your leased address.
