A, B, C class address is unicast address; D class address is multicast address; E class address is
reserved to prepare for the future for special purposes.
IP address using dotted decimal.
Each IP address is represented as four decimal integers separated by
decimal points, each integer corresponds to a byte, such as, 10.110.50.101.
Subnet Mask
Mask is corresponding 32 bits number of IP address. Some are 1, the others are 0. These 1 and 0 can
be combined arbitrary in principle, but the first continuous bits are 1 when designing subnet mask. IP
address can be divided into 2 parts by subnet mask: subnet address and host address. 1 in IP address
and subnet corresponds to subnet address, other bits are host address. A type of address
corresponding mask is 255.0.0.0; mask of B type address is 255.255.0.0; mask of C type address is
255.255.255.0.
Default Gateway
Default gateway in the host PC is generally called default route. Default route refer to a kind of router
that destination address of IP data packet will choose when it don’t find other existing route. All data
packets of destination address which don’t exist in the list of router will choose default route.
DNS Address
DNS (Domain Name Server) is for us to analyze domain to IP address of the Internet. If our
equipment needs to access a host, you need to use this server to resolve an IP address.
Device reboot
Can reboot the switch remote. Knock [Basic settings/Network&reboot] menu, Enter into reboot interface,
Figure as 6.11.1.
Knock<Reboot> button, after confirmation, device will be reboot. After 20 seconds, know menu bar
and back to WEB manged login interface.
