The router ID is used to uniquely identify each router in the OSPF routing domain.If no loopback interfaces are configured, the router chooses the highest active IP address of any of its physical interfaces.
Can router be traced to a preson through internet connection?
Because your router has a unique IP address (usually it's the case), your IP address can be traced back to the physical address (town, street, house, apartment), if you are registered as a resident at your current address people with certain skills will track you down for couple minutes.

Differentiate physical and logical addresses?
logical address and physical addressIn a system, there are two types of addresses: logical and physical. Another name for logical address is IP address and it is set by your Internet service provider (ISP) or your router. If you have a router then you have a LAN, which sets a logical address for your computer. Your router will have an logical address set by your ISP.The physical address is also called the MAC address and it is generated by the manufacturer. (but only to a given extent)Because a MAC address is assigned (by the FCC) to a company to use for a range of products.For example:01:23:45:00:00:00 - 01:23:45:FF:FF:FFWould be their "range" of MAC addresses. They use a coding called Hex which is not to far off from what you know which is base-10 (0-9).Instead hex uses (0-F). 0123456789ABCDEFA = 10, B = 11, etc.Read more: What_is_the_difference_between_logical_address_and_physical_addresses
What address does the router use to compare to the routing table?
in general the router uses the network address to compare to the routing table. Specifically, on the internet, the Router looks up the destination IP address in the router table to determine where to route the packet.
HSRP Configuration Cisco?
Hot standby router protocol. 2 different routers will have 2 different physical addresses, but you can give both of them a shared virtual address. only 1 router will answer on the virtual address at a time, but one goes down the other will take over.
Which two components are used to determine the router ID in the configuration of the OSPF routing process?
the highest IP address of any logical interfacethe highest IP address of any physical interface
Is there a way to determine a known IP address from a possible physical address?
A very intelligent question... Actually it is possible if you have an backdoor access to the switch or router of your ISP. If you know what I mean. But in general terms, it is NO!
What tcp ip configuration specifies the address of a router?
