This is actually a fairly common scenario in network servers.
There's no problem with two IP addresses living on the same adapter.

What is the difference between an Ethernet Address and an mac address?
Ethernet address is really not a good term to use. I think you mean a MAC address. A MAC address is given to any device that accesses the internet. Such devices include WiFi cards, modems, and routers. These are only used by networks that devices connect to, and not by websites. They can be used for filtering and identifying devices on a network.Ip (Internet Protocol) addresses are assigned to networks (one per network) by an ISP (Internet Service Provider) such as Comcast. These are sent to everything you interact with online, so that your network, rather than your computer, is identified.Now there are two kinds of Ip addresses: internal and external. Internal are used by your network to identify each device that connects to it. External Ip's are assigned by your ISP to identify you to the world. I explained the difference more in-depth in another answer, which is right here:What_is_the_difference_between_an_Ip_address_and_a_http_address
What are IP addresses called that begin with 172.16?
They are normally the IP addresses which your computer uses to talk to your internet router/modem. They are not the same as the IP address that your router is known by on the broadband link.
Can two computers have the same MAC address?
NO, its not possible to have same MAC addresses for two different network cards. because MAC address is a unique part of the recognition of the network card and it is also called as PHYSICAL address of your PC. There is possibility of 2 network cards with same MAC address by 3rd party MAC spoofing techniques.........
Which field in an IPv4 packet header will typically stay the same during its transmission?
Destination Address (I.P. ) will stay the same during transmission. But be careful! Only if it is Ip address. However if it is MAC it will change as it travels thru diferent routers with different MAC addresses to get to the destination Ip address (which does not change)!
Physical address and logical address?
A logical (or virtual) address is a reference to a memory location independent of the current assignment of data to memory; a translation must be made to a physical address before the memory access can be achieved. A relative address is the address expressed as a location relative to some known point, usually the beginning of the program. A physical address, or absolute address, is an actual location in main memory.
Can there be more than one Ethernet adaptors that have the same Ethernet MAC address?
One computer must have unique MAC addresses for each Ethernet adapter (ideally each Ethernet adapter in existence has a unique MAC address but there are some that allow manual setting of the MAC, so duplicates can exist.) If you have not changed anything from the factory settings then each network card will have a unique address!
What kinds of problems can arise when two hosts on the same Ethernet share the same hardware address?
dear all, hardware address is unique so their is no chance of same Ethernet share. thanks Raj
When and where can use the IP-address and the MAC-address?
802.11 use MAC addresses, which are the same as IP addresses in some networks
In modem what kind of address is used?
If your talking about a dial-up modem, it uses a public IP just like a ethernet card. It depends on your ISP, what range of IP addresses you are assigned when you connect (DHCP: automatically assigned IP address; IP address can change) or you could also have a static address( IP address is always the same).
What happens if an ip address is given for more than one user?
In the same network this cannot happen because the IP addresses need to be unique. Any device that tries to duplicate an address will not receive one.
Why is email addresses unique?
The same reason your house address is unique. To address mail to a specific destination.

How are IP addresses assigned from a pool of IP addresses?
That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned. Any time a host (computer or similar) requests an IP address, the DHCP server will assign an available address and mark it, in its memory, as "assigned" so it won't assign the same address to another computer.That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned.

What is true regarding media access control?
The question is a little vague, but a media access control (MAC) address is an address assigned to network interface devices such as an Ethernet card or wireless card. The addresses are assigned by the manufacturer and no two cards share the same number; each must be unique.
Do you share your IP address with other internet users in your house who use the same wireless internet 'network' as you?
Within the local network, every computer has to have a different IP address. These IP addresses have to be in the same subnet; usually this means that the first 3 bytes are the same.Within the local network, every computer has to have a different IP address.

Bridges in networking?
A Bridge operates at 1. Physical layer: (a) divides large LAN into segments (b) connects 2 LANs that use same protocol. e.g. if the protocol is Ethernet then it can connect Fast Ethernet with Gigabit Ethernet. 2. Data link layer: (a) PDU of this layer is called frame. (b) Bridge can understand only the MAC addresses, so it forwards the frames according to their MAC addresses (unique address of NIC) to the next segment (same protocol) A bridge does not operate at net layer so it can't understand IP addresses & therefore cant recognize protocols. Thus it can't connect 2 LANs with different protocols. e.g. it can't connect Ethernet with Token Ring or FDDI. A bridge uses an interface address table to know which computers are connected to which segments. Entries in this table are SOURCE from which the bridge has received the frame & the PORT (MAC) address. By doing this it can know which computer is connected to which port Working: When a Bridge receives a frame, it checks the destination address of the frame. If the destination is present in the interface address table, it forwards the frame. If the destination is not present in the table, the bridge broadcast the frame on the all outgoing ports (except the port from which it arrived). This is called flooding.
What is need of logical to physical address translation?
== == I'm not a vandal or spammer I just haven't created a username and password yet but the answer to the question is that your physical address is burned into the net work card adapter on your PC or on Apple Macs by the manufacturer at the time of production and they are all unique. That physical address, just like your mailing address it is real, is also called your MAC address (Media Access Control address) and looks like this 00-56-7E-4A-DD-8D. The logical address is what the IP (Internet Protocol) address, can also be called virtual address, is and it looks like this 216.109.112.135 and is Yahoo's IP address. Your IP address can change and often does when you have a high speed Internet connection. This is called your DHCP Lease and it actually has an expiration date and time. When it expires you may get the same one or another one depending on what available IP addresses the DHCP server has available. You can also do this with the release and renew commands. You can look up the addresses on your computer with the ipconfig -all command in Windows command line utility (cmd on 2000/XP). To do this go to Start - RUN - type 'cmd'. Then your console window should open up. In there you can type 'ipconfig -all' and you will get the information about your physical address and IP address. To lookup Yahoo's or Google's address type ' nslookup yahoo.com or nslookup google.com and you should get the corresponding IP address of the web site. nslookup (name server lookup) is a network command line utility that will display the IP address of a site. I hope this helps as there is a great deal more information that I could write about these two address types.
