1 Introduction to VMware Three network modesVMware offers three modes of operation, which are bridged (bridging mode), NAT (network address translation mode), and host-only (host mode). after installing the virtual machine, you can see more than two NICs in the network connection. Such as. 2 bridged (bridging mode) 2.1

recently take an exam, always encounter the problem of MAC address, so in the online to do a knowledge collation, remember these knowledge or sophomore time learned, has basically returned to Huang teacher, but thank him patiently and responsibly to teach us the principle of computer knowledge, At least remember that he had brought us a lot of good college memories. MAC address and IP

. Input and output formats follow classless Internet Domain Routing conventions. The format for specifying networks are address/y where address is the network represented as an IPV4 or I Pv6 address, and y are the number of bits in the netmask. If y is omitted, it's calculated using assumptions from the older

IPV4 Address:We know that at the network layer (the Internet layer of TCP/IP architecture), one of the most important protocols is IP protocol, is now in the IPV4 and IPv6 transition period, but at present, IPV4 is still mainstream, so the main Ipv4.Basic IP Address format:The format of the internal IP address of the computer is represented by a 32-bit binary num

IP address is a unified address format provided by IP protocol, which assigns a logical address to each network and each host on the Internet, so as to shield the difference of physical address. The physical address of the NIC is
