ip address questions

Hi there, I have some questions in my mind and would like to get your kind help plz:

1- I know each computer on the internet has a unique ip address, and each website online has an ip address. My question is what is the difference between ip of computer and ip of website. are they treated the same.

2- I know that the website ip is a representative number for the domain letters. Is the dns rule only to match the domain letters with its ip number?

3- in dynamic ip, how we know that this computer has sent this data, knowing that the ip is changing from time time.

4-does the computer ip contain part of the mac?

thanks indeed

    1 - website doesn't have an ip address. The server which hosts that website does.
    Server is basically same thing as your computer.There are 2 kinds of IP addresses -
    private and public. Private addresses ( starting with 192.168. , 10. , 172.16. ) .
    Private addresses are not routed into the internet. You use them in your local home or company network. I.e. you have your router at home which has public IP and it 'masks' your private addresses to his public IP - so when you i.e. browse the internet - you're seen as the IP address of your router. Note that your router can also have private address and the next or following router can do the translation. But in the end you will have some sort of public IP. Of course you can also be connected with public ip directly - depends on your network configuration and ISP.

    2 - Mainly yes DNS maps ip addresses to names. Not website names. Host/Server names.
    It can also store some more information, i.e. text records, mx records - which mail servers use to know where to send emails.

    3 - ISP providers have to log to whom they given which address at what time.

    4 - IP if you mean the number - no - it's just a number nothing else. What you probably mean is IP protocol . MAC address is unique ( should be ) for any device. Computers to communicate in local network needs to know each other MAC address, IP is not enough.
    So to translate IP address to MAC address a protocol called ARP is being used.
    If you ask is your MAC address passed into internet by IP - then rather no - MAC address is lost after next router jump AFAIK
