albertlee Posted July 19, 2004 Share Posted July 19, 2004 I have a dynamic IP address, and is there any free DNS server software that automatically change the IP of domain name, so I dont have to change it my self every time I re start my computer?

admiral_ju00 Posted July 19, 2004 Share Posted July 19, 2004 Good question. I don't think that there is such a software. Why do you need it for anyway(a better elaboration of the post 1 would be nice) since that your DHCP info IS dynamic and is therefore subject to change anyway - unless you specify one manually and save it?

Sayonara Posted July 19, 2004 Share Posted July 19, 2004 What are you trying to do? Host a domain on your own box? If I remember correctly LuTze did something similar a while ago. Link to comment Share on other sites More sharing options...
albertlee Posted July 21, 2004 Author Share Posted July 21, 2004 yeah, Sayonara, I want to have my own website and own domain on my box with DHCP, but I would like to ask, does IP only change when I restart my computer? secondly, can I make my own domain name server without any cost if my top level domain does not even exist before? if my domain is not under like .com .uk .us etc...?

JaKiri Posted July 21, 2004 Share Posted July 21, 2004 If you've got a dynamic IP, it changes every time you reconnect to the net. Link to comment Share on other sites More sharing options...
LuTze Posted July 21, 2004 Share Posted July 21, 2004 Firstly no, you can't just dream up your own TLD's (.com, .net, .org, etc). They're decided on by ICANN. DNS works sort of like this. When your computer tries to look up a domain name, we'll say http://www.google.com for example - it will ask your ISP's DNS server what the IP for that name is. The ISP's server will look at the .com bit, and ask something called a "root server" about it. It's these root servers where the whole thing begins. They know about all the TLD's and think "Oooh, I know who to ask about that. Thats Verisign!", so it tells the ISP's server to and go off and ask Verisign's DNS server "who's Google"? Verisigns DNS server will reply with the IP's of Google's very own DNS servers which are then asked by the ISP's server "Whats the IP address for www.google.com?", and it'll get a reply. So you see the problem with inveting your own TLD's is that the root servers won't have a clue whats going on. Thats a simplified version of whats going on, because DNS really is complicated and terribly dull. If you'd like to know more there is a book called "DNS & Bind" by O'Reiley that explains it all in excruciating detail. Second, the IP you get from your ISP will probably change each time you reboot. It can even change when you haven't rebooted for a while. You can dynamically change DNS records based on your current IP easily and there are a few services that will do it. Some for free, some cost. I use http://www.dyndns.org myself. There are lots more. Try a Google search for "Dynamic DNS". Hope that helps. Link to comment Share on other sites More sharing options...
e(ho0n3 Posted July 21, 2004 Share Posted July 21, 2004 yeah, Sayonara, I want to have my own website and own domain on my box with DHCP, but I would like to ask, does IP only change when I restart my computer? Your IP changes everytime you connect to the internet (or whatever network you are on that is running DHCP) or when the lease time of the IP you were given expires. secondly, can I make my own domain name server without any cost if my top level domain does not even exist before? if my domain is not under like .com .uk .us etc...? No. Top level domains are given to you. If you want a DNS server, try BIND. It's very powerful. Running a DNS server for one website is overkill in my opinion. Just ask your ISP to do it for you.

albertlee Posted July 22, 2004 Author Share Posted July 22, 2004 But I really want to ask, how can people make their own top level domains, like .cc for example? because my friend has websites under that domain...... Albert Link to comment Share on other sites More sharing options...
Sayonara Posted July 22, 2004 Share Posted July 22, 2004 They can't. See here for .cc info: http://www.yfiles.com/cc.html Link to comment Share on other sites More sharing options...
Dave Posted July 22, 2004 Share Posted July 22, 2004 There is a seperate NIC you can use called OpenNIC. I don't know how widespread it is, but they've basically come up with a set of their own root servers because they're fed up with the red tape that comes along with the setting up of TLD's (partly, at least). Don't know how many people use it, but I use their nameservers as they will obviously resolve all of the existing domains. Link to comment Share on other sites More sharing options...
mossoi Posted July 22, 2004 Share Posted July 22, 2004 Have you checked with your ISP to see if they'll give you a static IP? I'm hosting a couple of sites on my machine and I got a static IP for no extra cost. Link to comment Share on other sites More sharing options...
