1) the mac address stays the same in the packet so it knows where it comes from, the IP address is changed when it leaves the port of the switch / router and it will then add in the next hop info. The destantion IP address will always stay in the packet so it knows where it needs to go to. the mac address will be the next hop.
Re: How to explain Source IP Address, Destination IP Address & S When using a document - that is the easiest way. I find the best way is to have a conversation with the remote person. The IP protocol uses the IP address specified in the destination IP field and the subnet mask to extract the destination IP network address to which the datagram must be routed. The IP protocol looks up in its routing table to determine whether the destination network is directly accessible by the node or whether it needs the router to route An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing. The destination address can be one of the following: The physical address, such as the MAC address of an Ethernet frame; The logical address, such as the IP address of an IP packet; Destination addresses can be either specific or general. Specific addresses point to a specific host on the network. Re: source and destination ip address just to correct me if im on remote location (33.33.33.33) and i need to have an access to some servers on Head office site (22.22.22.22) so in that case the source ip should me ip addresses of the machines that already connected to remote location where traffic coming from
Instantly Locate Any IP Address This free online tool allows you to see the geographical location of any IP address. Just input the IP address and you will be shown the position on a map, coordinates, country, region, city and organization.

(Geolocation) IP-based Geolocation is mapping of an IP address or MAC address to the real-world geographic location of an Internet-connected computing or a mobile device. Geolocation involves in mapping IP address to the country, region (city), latitude/longitude, ISP and domain name among other useful things.
The source IP in other words, assuming that all devices has IP addresses. A device that initiates a communication, its IP address is consider as the source IP. To Who?
Source Address Range: Specify the source IP address (or address range) to match. IP address ranges use the format ip/netmask (where netmask is in bits 1-32). This may be left blank for Any. Destination Range: Specify the destination IP address/address range to match. The IP address enables the clear forwarding and sending of data packets from the source to the destination. As with a telephone number, this address can be divided up into area code and telephone number – but for IP addresses, this is known as the network part and host part. Therefore, in most cases the second destination IP address is not the same as the first IP address. The port numbers can be the same when you are configuring two unique destination IP addresses. If you want to configure both instances of the command to use the same destination IP address, you must use unique port numbers. For getting the destination IP address there are two ways based on the fact that whether you are a visitor or a client . If you are a visitor and you want to check the IP address ,you can ping the domain name on your cmd like - ping redserverhost. The PC now has the correct IP address for the URL it wishes to contact, so it can construct a new packet containing the web server as a destination and carrying an HTTP GET message requesting webpage content.
