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.
