Is our IP address always the same?

Would a Mac address be another name for IP address?

  • Which four items of information are required for TCP/IP network configuration? (Choose four.) -IP address of host - subnet mask -MAC address -IP address of default gateway -IP address of DNS server -host name The three I know for sure are: - subnet mask -IP address of default gateway -IP address of DNS server But idk the 4th one. All i know is that the fourth one isnt: Hostname. This is what the book says: To configure TCP/IP, the user needs the following information: * IP address * Subnet mask * Default gateway * IP address of DNS server(s) Would a Mac address be another name for IP address?

  • Answer:

    The one you are looking for is the IP address of the host. You can see an IP address sort of like a phone number for a computer or device. When making a TCP/IP connection, the host (your computer) needs to be connected with a gateway (which is the first hop of several to reach the internet) and a DNS server (which is sort of like a phone book... it takes that name you type into a web browser (www.yahoo.com) and finds the corresponding IP address (69.147.114.210) so that you can reach it. Most of the time your internet service provider will provide you with an IP address for your computer. Sometimes they give you one that will not change (a router will do the same. This is a "static" IP address) and sometimes they will give you a different one every couple of days. (a "dynamic" IP address.) The Subnet Mask is just a networking tool that identifiest he class of your IP address and is more important in large networks, not so much in a home inernet connection. The MAC address is the physical address of a computer device. It is embedded on the device, never changes, and is in the format 11:19:ef:13:fc:a4.

No, a MAC address (e.g. - 00-08-74-4C-7F-1D) is hard coded into your network card, whereas an IP address (e.g. - 192.168.0.1) is configured in your OS.

No, they are not the same. A MAC address is a unique number that comes from the manufacturer while the IP address is a "number" that you get from a DHCP server or you normally assign to a PC. Check the article below- http://compnetworking.about.com/od/networkprotocolsip/l/aa062202a.htm

No a MAC address is not another name an IP address, your MAC doesn't change, your IP does. IP address of host would be the 4th.

No. IP is part of TCP/IP and can change depending on your settings. A mac address is the physical address of a card or device (router, printer, etc...) and is hard coded into the device so will never change.

No. MAC address : The MAC address is a unique value associated with a network adapter. MAC addresses are also known as hardware addresses or physical addresses. They uniquely identify an adapter on a LAN. MAC addresses are 12-digit hexadecimal numbers (48 bits in length). By convention, MAC addresses are usually written in one of the following two formats: MM:MM:MM:SS:SS:SS MM-MM-MM-SS-SS-SS The first half of a MAC address contains the ID number of the adapter manufacturer. These IDs are regulated by an Internet standards body (see sidebar). The second half of a MAC address represents the serial number assigned to the adapter by the manufacturer. In the example, 00:A0:C9:14:C8:29 The prefix 00A0C9 indicates the manufacturer is Intel Corporation IP address : The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.

Nope, each network card has it's own MAC address which is kind of like a serial number. A MAC address is not used for TCP/IP connections, unless some security device is verifying it is your computer. A MAC address is used by your computer to know which network card. So for instance, you have 2 network cards, each card has its own unique MAC address, then the computer which MAC address to send information to. To configure TCP/IP, you need: 1. IP Address 2. Subnet Mask 3. Default Gateway 4. DNS Server address HTH

Hi superstar6592, I would recommend you writing down this information and asking your Internet Service Provider. They should have a technical help phone number to call and they should have the answers for you. It may not be named exactly the same way, but they should be able to help you with all of those numbers and names that you need to get you connected and getting your e-mail set up. Many ISPs will have Macintosh knowledgeable staff on hand to help you with any problems. That's part of what you pay them for. If they can't or won't help you, then you may seriously need to look at other ISPs for your Internet. Best of luck to you. --Rick

Of course...MAC = IP address, but on a MAC computer.
