The Router only has one M.A.C Address and One IP Address But, the Router can have many Connections ( Devices using the network ) That may shoe up as their IP Addresses. But the Router only Has One IP Address
IP address remains the same. Mac address changes from router to router.
A switch uses MAC address to forward frames while a router uses IP addresses.
Router can get your MAC address, IP address and computer name.
i want settings mac address my router...only internet access by mac
Source or Destination MAC address
It is a list on your internet router that filters computers by their MAC address, which is the fingerprint of the network adapter.
It uses the MAC address, Media Access Control. Every packet sent from a computer contains its MAC address. The router stores this in its routing table. When it receives a packet with a destiation address of that MAC address, then it forwards it to that computer. This is called NAT, Network Address Translation. It uses the Destination IP address
MAC address filtering uses the MAC address to identify which devices are allowed to connect to the wireless network. When a wireless client attempts to connect, or associate, with an AP it will send MAC address information. If MAC filtering is enabled, the wireless router or AP will look up its MAC address a preconfigured list. Only devices whose MAC addresses have been prerecorded in the router's database will be allowed to connect.
no a bridge does not use a IP address, it uses MAC address', rousters or layer 3 uses ip address.
Sometimes a router has the option to exclude all connections apart from certain specific devices. It is those devices' MAC addresses that you will need to enter in order for the router to indentify them.
If a switch is connected to a router then the MAC address of the router is known to the switch through that port. A host takes advantage of this by using the default gateway address (the address of the router) which the switch "knows" by its lookup table. Therefore, the switch can learn the address automatically and no configuration is necessary.
Often, this means MAC masquerading. MAC is the unique hardware address to an ethernet adapter. For instance, your computer would have one MAC address for a wired ethernet port, and another for a wifi adapter.Masquerading means passing off another MAC as the one actually belonging to the adapter.Example:You have a cable modem connected to your cable ISP, and a single computer connected to the modem. Your computer wired ethernet MAC is 11:22:33:44:55:66.You go out and buy a new wifi router+access point, and try to connect it to the modem, and connect your PC to the access point via WiFi. It doesn't work. You connect to the access point but not the internet.Why not?When your modem was initially set up with the ISP, the ISP "provisioned" (allowed access to) the MAC address of your PC (11:22:33:44:55:66).Now that the router is connected to the modem, the ISP sees the MAC address of the router (99.88.77.66.55.44) and does not see the "allowed" MAC address of your PC because your PC is no longer directly connected to the ISP.Proper fix: Call ISP and re-provision the new MAC address of the router.Quick fix: set up the router's MAC masquerading function to transmit the old PC MAC address instead of the router's MAC, tricking the ISP into thinking the old hardware is still connected.
