A DHCP server can manage IP settings for devices on its local network, e.g., by assigning IP addresses to those devices automatically and dynamically. [11] DHCP operates based on the client–server model. When a computer or other device connects to a network, the DHCP client software sends a DHCP broadcast query requesting the necessary ...
The Dynamic Host Configuration Protocol version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes, default route, local segment MTU, and other configuration data required to operate in an IPv6 network.
The IP guard initially blocks all traffic except DHCP packets. When a client receives a valid IP address from the DHCP server the IP address and switch port relationship are bound in an Access Control List (ACL). The ACL then restricts traffic only to those IP addresses configured in the binding. [9]
Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
It is a link layer based protocol to configure station names and IP addresses. It is restricted to the local network segment and mainly used in small and medium applications without an installed DHCP server. [1]
In addition, information on hosts which have successfully completed a DHCP transaction is accrued in a database of bindings which may then be used by other security or accounting features. [2] [3] Other features may use DHCP snooping database information to ensure IP integrity on a Layer 2 switched domain. This information enables a network to:
Internet Connection Sharing (ICS) is a Windows service that enables one Internet-connected computer to share its Internet connection with other computers on a local area network (LAN). The computer that shares its Internet connection serves as a gateway device , meaning that all traffic between other computers and the Internet go through this ...
The CWMP protocol also defines a mechanism for reaching the devices that are connected behind NAT (e.g. IP-Phones, Set-top boxes). This mechanism, based on STUN and UDP NAT traversal, is defined in document TR-069 Annex G (formerly in TR-111).
