... Assignment may be temporary: Address “leased” to a client
for a limited time.
SENS supports DHCP client, server and relay agent operation
... Transparency – Host names remain constant even
when associated IP address change.
Ease of Use – Use names to access resources instead of
numerical IP addresses.
Simplicity – Users need to learn only one naming
convention to find resources on the Internet.

Describe four (4) services that are part of the
TCP/IP protocol suite that would probably be
implemented within a network centre to manage:
• naming within legacy systems
• automated issuing of IP Addresses
• name to IP Address translation
• private IP addressing

NetBIOS name resolution
... The first issue is determining the kind of name. In the Windows client world, there are two basic
types of names. The first kind is a name for IP addresses. Host name resolution uses a host’s file
and DNS for resolution. The second kind of name is the NetBIOS name, which is used for Windows

and reverse mappings (IP address to host names)

on a host machine sends out a request on the

• A dhcp server will answer and lease an IP
address to the host, sending it the network mask

Zero-configuration networking (zeroconf) is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite (TCP/IP) when computers or network peripherals are interconnected. It does not require manual operator intervention or special configuration servers.Zeroconf is built on three core technologies: assignment of numeric network addresses for networked devices, automatic distribution and resolution of computer hostnames, and automatic location of network services, such as printing devices. Without zeroconf, a network administrator must set up services, such as Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS), or configure each computer's network settings manually.
