IP address: An IP address is a 32-bit length address assigned to a device
connected to the Internet. An IP address consists of two fields: a network
number field (net-id) and a host number field (host-id). The IP address is
assigned by the Network Information Center (NIC) of the US Defense Data
Network. To facilitate the management of IP addresses, IP addresses are
classified into five categories: A, B, and C addresses are unicast addresses;
Class D addresses are multicast addresses; Class E addresses are reserved
addresses for future use. Special use. Currently, a large number of IP
addresses in use belong to the A, B, and C addresses.
Subnet mask: A mask is a 32-bit number corresponding to an IP address.
Some of these numbers are 1, and others are 0. The mask can divide the IP
address into two parts: the subnet address and the host address. The part of
the IP address corresponding to the bit in the mask is the subnet address, and
the other bits are the host address. The mask corresponding to the class A
address is 255.0.0.0; the mask of the class B address is 255.255.0.0; the mask
of the class C address is 255.255.255.0.
Default Gateway: The default gateway in the host is often referred to as
the default route. The default route is the route selected by the router when no
other route exists in the destination address of the IP packet. The default route
is used for all packets whose destination is not in the router's routing table. This
route will usually go to another router, and this router will also process the
packet. If you know how to route the packet, the packet will be forwarded to the
known route; otherwise, the packet will be forwarded to the default. Route to
reach another router.
Attention:
1. When entering the waiting page after configuring IP, do not power off
or perform other operations to avoid IP address modification failure.
2.The configured IP address and default gateway need to be in the
same network segment.
4.7.2. User name
