The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture.
Example showing how DHCP snooping works. In computer networking, DHCP snooping is a series of techniques applied to improve the security of a DHCP infrastructure. [1] DHCP servers allocate IP addresses to clients on a LAN. DHCP snooping can be configured on LAN switches to exclude rogue DHCP servers and remove
The Web Proxy Auto-Discovery (WPAD) Protocol is a method used by clients to locate the URL of a configuration file using DHCP and/or DNS discovery methods. Once detection and download of the configuration file is complete, it can be executed to determine the proxy for a specified URL.
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.
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.
The adversary can then set up a rogue DHCP server so that clients receive incorrect network settings and as a result transmit data to an attacker's machine. [8] One method for mitigating this type of attack is to use the IP source guard feature available on many Ethernet switches. The IP guard initially blocks all traffic except DHCP packets.
In fact, McDonald believes he's best suited for guard, and the Cowboys feel likely to let Martin leave, after all. From McDonald in our mock draft 3.0 : Banks is explosive, plays balanced and can ...
An example of the effect of IGMP snooping on the traffic in a LAN. IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic to control delivery of IP multicasts.
