Loose Source Routing is an IP option which can be used for address translation. LSR is also used to implement mobility in IP networks. [3] Loose source routing uses a source routing option in IP to record the set of routers a packet must visit. The destination of the packet is replaced with the next router the packet must visit.

This routing header was designed to support the same use cases as the IPv4 header options. As there were several significant attacks against this routing header, its utilisation was deprecated. [6] A more secure form of source routing was being developed within the IETF as of 2017 to support the IPv6 version of segment routing. [7]
IP forwarding algorithms in most routing software determine a route through a shortest path algorithm. In routers, packets arriving at an interface are examined for source and destination addressing and queued to the appropriate outgoing interface according to their destination address and a set of rules and performance metrics.
An IP packet has no trailer. However, an IP packet is often carried as the payload inside an Ethernet frame, which has its own header and trailer. Per the end-to-end principle , IP networks do not provide guarantees of delivery, non-duplication, or in-order delivery of packets.
In Linux terminology, a Martian packet is an IP packet received by the kernel on a specific interface, while routing tables indicate that the source IP is expected on another interface. [ 3 ] [ 4 ] The name is derived from packet from Mars , meaning that packet seems to be not of this Earth.
A routing table is a data file in RAM that is used to store route information about directly connected and remote networks. Nodes can also share the contents of their routing table with other nodes. The primary function of a router is to forward a packet toward its destination network, which is the destination IP address of the packet.
The IP-address could be 91.198.174.2. In this example, none of the internal routers know the route to that host, so they will forward the packet through router1's gateway or default route. [1] Every router on the packet's way to the destination will check whether the packet's destination IP-address matches any known network routes.
