A rogue DHCP server is a DHCP server on a network which is not under the administrative control of the network staff. It is a network device such as a modem or a router connected to the network by a user who may be either unaware of the consequences of their actions or may be knowingly using it for network attacks such as man in the middle.
This is a list of Hypertext Transfer Protocol (HTTP) response status codes. Status codes are issued by a server in response to a client's request made to the server. It includes codes from IETF Request for Comments (RFCs), other specifications, and some additional codes used in some common applications of the HTTP. The first digit of the status ...
IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic to control delivery of IP multicasts. Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need which IP multicast transmission. Multicasts may be filtered from the ...
Before claiming an IP address, the client should probe the newly received address (e.g. with ARP), in order to find if there is another host present in the network with the proposed IP address. [ 8 ] : sec. 2.2 If there is no reply, this address does not conflict with that of another host, so it is free to be used.
All forms of port scanning rely on the assumption that the targeted host is compliant with RFC.Although this is the case most of the time, there is still a chance a host might send back strange packets or even generate false positives when the TCP/IP stack of the host is non-RFC-compliant or has been altered.
Deep packet inspection (DPI) is a type of data processing that inspects in detail the data being sent over a computer network, and may take actions such as alerting, blocking, re-routing, or logging it accordingly.
The Address Resolution Protocol (ARP) is a communication protocol for discovering the link layer address, such as a MAC address, associated with a internet layer address, typically an IPv4 address. The protocol, part of the Internet protocol suite , was defined in 1982 by RFC 826 , which is Internet Standard STD 37.
IP addresses are assigned to a host either dynamically as they join the network, or persistently by configuration of the host hardware or software. Persistent configuration is also known as using a static IP address. In contrast, when a computer's IP address is assigned each time it restarts, this is known as using a dynamic IP address.
