127.0.0.1 is the loopback address in IP.... or in the (slightly modified) words of Dorthy Gale when she returned from Oz "There's no place like 127.0.0.1"
There are two address fields. Source is the IP address the packet came from and destination is the IP address the packet is meant to be delivered to.
That is called an IP address.

Router uses IP address of destination node to do the direct packet switching..while bridge & switch uses the MAC address to packet forwarding.
To send data from host A to host C, host A will use the IP address of host C as the destination address in the IP packet header. Additionally, the MAC address of host C will be used as the destination address in the data link layer frame. If host C is on a different network, host A will also need to send the packet to its default gateway, using the gateway's MAC address for the initial transmission.
The address 127.0.0.1 is commonly referred to as "localhost" or the "loopback address." It is used to establish a connection to the same machine or computer that a user is working on, allowing for testing and development of network applications without the need for an external network. This address is part of the IPv4 standard and is reserved for loopback purposes.
Which portion of the destination IP address is used as a packet is routed through the Internet?
The address 127.0.0.1 is known as the loopback address in Internet Protocol (IP) networking. It is used by a computer to refer to itself, allowing for testing and communication within the same machine without involving external networks. This address is part of the reserved IP address range defined for loopback purposes, typically associated with the hostname "localhost."
Destination address
ARP stands for Address Resolution Protocol. This is IP's way of requesting a MAC address (or hardware address) from a host located at a certain IP address. In order for a host on a network to send a unicast packet across the network, it must know both the source and destination MAC addresses. ARP is used to obtain a MAC address similar to the way DNS is used to obtain an IP address from a domain name (www.anydomain.com).
There are two address fields. Source is the IP address the packet came from and destination is the IP address the packet is meant to be delivered to.
Internet Protocol, or IP, puts a header on every packet that it sounds out. This header is the overhead. All protocols, such as TCP or UDP, will put a header on the packet. The IP header contains information such as source IP address and destination IP address and is used by routers to figure out where to send the packet. ex. you send your friend a 1kb file, but it takes up 1.5kb of bandwidth due to overhead
resever ip of loop back is 127.0.0.1
That is called an IP address.
