HUB
A network hub or concentrator is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single network segment.
Router
A router is a computer whose software and hardware are usually tailored to the tasks of routing and forwarding information.
Switch
A network switch is a computer networking device that connects network segments.
Ping
Ping is one of the most useful network debugging tools available.
In an IP network.
`ping' sends a short data burst - a single packet - and listens for a single packet in reply. Since this tests the most basic function of an IP network (delivery of single packet)

IP-TOKEN(8) Linux IP-TOKEN(8)
NAME
ip-token - tokenized interface identifier support
SYNOPSIS
ip token { COMMAND | help }
ip token set TOKEN dev DEV
ip token del dev DEV
ip token get [ dev DEV ]
ip token [ list ]
DESCRIPTION
IPv6 tokenized interface identifier support is used for assigning well-known host-part addresses to nodes whilst still obtaining a global
network prefix from Router advertisements. The primary target for tokenized identifiers are server platforms where addresses are usually
manually configured, rather than using DHCPv6 or SLAAC. By using tokenized identifiers, hosts can still determine their network prefix by
use of SLAAC, but more readily be automatically renumbered should their network prefix change [1]. Tokenized IPv6 Identifiers are described
in the draft [1]: <draft-chown-6man-tokenised-ipv6-identifiers-02>.
ip token set - set an interface token
set the interface token to the kernel.
TOKEN the interface identifier token address.
dev DEV
the networking interface.
ip token del - delete an interface token
delete the interface token from the kernel.
dev DEV
the networking interface.
ip token get - get the interface token from the kernel
show a tokenized interface identifier of a particular networking device. Arguments: coincide with the arguments of ip token set but the
TOKEN must be left out.
ip token list - list all interface tokens
list all tokenized interface identifiers for the networking interfaces from the kernel.
