Discussion Overview

The discussion revolves around the differences between static and dynamic IP addresses, including their applications, limitations, and preferences among users. Participants explore the implications of using each type of IP address, particularly in relation to hosting servers and DNS functionality.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant inquires about the differences between static and dynamic IP addresses and their respective limitations in various situations.
  • Another participant asserts that dynamic IP addresses complicate DNS usage, making it harder to connect to servers without remembering changing IP addresses.
  • It is noted that some services restrict access based on IP addresses, suggesting that a static IP may be necessary for broader accessibility.
  • One participant confirms that the original poster's IP address is dynamic, as indicated by the changing host ID.
  • There is a counterpoint that running servers on a dynamic IP address is possible, although it may be inconvenient for public access.
  • Another participant reiterates the inconvenience of using a dynamic IP for server processes, emphasizing the need for a DNS name for stable access.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of running servers with dynamic IP addresses, with some asserting it is inconvenient while others argue it is entirely possible.

Contextual Notes

The discussion reflects varying assumptions about the practicality of dynamic IP addresses in server hosting and the role of DNS in mitigating issues related to changing IPs.

My books tell me static and dynamic IP addresses are different but could you tell me which one do you prefer to have and why ? what can you do with static IP address and with dynamic one ?I mean their limitations, in what situations etc..?

I have a ip : 218.227.208.5 delivered by my ISP, when I log on the first time it becomes 218.227.208.5, the second time it becomes 218.227.117.154
My Ip is dynamic ?? :confused:

Please help newie
Thank you very much...

You can't do DNS with a dynamic IP address. That makes it harder to do stuff with a server as now instead of remembering www.mydomain.org[/URL] you have to remember 208.172.34.3 or something like that, not to mention it will change frequently (at most places).

Also, I know of some services (that use ssh and https) that will restrict access based on IP, which pretty much rules out having a dynamic IP.

I do run servers with dynamic IP (and even behind a firewall), but if you want it to be used by the masses then you definitely need a static IP.

Clearly your address is dynamic, because the host ID changes!
If you run server processes in your computer, clients cannot connect to it by specifying the IP address. You would need a DNS name.

This is not right. You can run servers with a dynamic IP address. Its just that your address might change making it incovenient for public use.

That's what I meant, actually. Non-convenience.
