If the answer is possible,how?

DNS is not for this kind of job,obviously.

UPDATE

Can someone answer this question:

domain name : IP -> DNS;

IP : Mac -> ??

Yes, of course it is. You can add an alias for your NIC that gets a different IP adress or add a second NIC with a different IP.

How this is done varies with the OS used, which you didn't state.

  • Do you mean I need to have multiple NIC to host multiple IP address? – apache May 07 '10 at 10:39

    @apache: No. You can have multiple IP addresses on a single NIC. – Benoit May 07 '10 at 10:41
  • How's it added ? What's the name of that X(device?) to add it(like DNS)? – apache May 07 '10 at 10:43
  • maybe if you told us your operating system, that might help. – Chopper3 May 07 '10 at 10:44

    I'm using windows XP, using ADSL. I doubt how I can add/change the IP without authentication. – apache May 07 '10 at 10:46
  • ah, if you're using adsl then simply adding the extra IPs to your existing NIC may very well not do what you need - your adsl provider needs to know that you're exposing multiple IPs over their connection to route correctly. – Chopper3 May 07 '10 at 11:06

    OK, if you try to get a second public IP address for your DSL line, you are probably out of luck as I never heard of any provider who would offer that. Please extend your original question with some info on what you want to do and why. – Sven May 07 '10 at 11:07
  • @SvenW,can you answer this question: domain name -> IP : DNS;IP -> Mac : ?? – apache May 07 '10 at 11:11
  • @apache: If I'm reading your symbols correct, I believe you're asking what translates an IP address to MAC address? That would be ARP, Address Resolution Protocol. – jscott May 07 '10 at 12:29

    Sorry, I don't understand this question. Domain name and DNS are the same for me, and I don't see how the MAC address matters here. Please try to explain what you want to do. – Sven May 07 '10 at 12:31
  • ARP is a protocal, where is the IP-to-MAC information restored? – apache May 07 '10 at 12:32
  • You are right, ARP is a protocol which works on the local (Ethernet) network only, not beyond it: Some system want's to send a packet to 192.168.1.100 and sends a broadcast: Who was this adress? The system with this address then sends an answer: I have, you can reach me with this MAC adress. Then the sender sends an ethernet packet to the MAC address it received and stores this info in it's ARP cache so it doesn't have to ask every time. Again, please explain what you want to do. – Sven May 07 '10 at 12:46

On Windows, go to the properties of your network connection, then in the TCP/IP properties, then click "Advanced". You can add additional IP addresses there.

You can buy an IP Pool from your ISp and ask them to bind the IP pool to your master IP. They will update on their DNS so any query for any of the IP addresses in the pool will come to you. Nice way of separating services.
