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.
Which portion of the destination IP address is used as a packet is routed through the Internet?
Destination address
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."
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.
Defining a voice and WAAS (Wide Area Application Services) loopback interface, such as Loopback1, is essential for ensuring consistent routing and management of network traffic. The loopback interface provides a stable, virtual endpoint for network protocols and services, enabling reliable communication without dependency on physical interfaces. By assigning a specific IP address (in this case, 10.30.15.254) with a subnet mask of 255.255.255.255, it ensures that the loopback can be used for monitoring and troubleshooting purposes, as well as for application optimization in WAN environments.
There are several IP addresses that are special in one way or another. These addresses are for special purposes or are to be put to special use.Addresses significant to every IP subnet Network AddressBroadcast AddressAddresses significant to individual hosts Loopback AddressSpecial Addresses of Global Significance Private AddressesReserved AddressesLOOPBACK ADDRESS (127.0.0.1)The 127.0.0.0 class 'A' subnet is used for only a single address: the loopback address 127.0.0.1. This address is used to test the local network interface device's functionality. All network interface devices should respond to this address. If you ping 127.0.0.1, you can be assured that the network hardware is functioning and that the network software is also functioning.
