Explain how IP addressing works.IP addresses are 32-bit addresses written as four octets in dotted-decimal notation, such as 192.168.5.18. To communicate on an IP network, a host also needs a subnet mask, which may look something like 255.255.255.0.What DHCP and DNS do? On TCP/IP networks, the DHCP server can provide IP configuration information to hosts. A DNS server resolves hostnames ...
