Server DHCP is used for dynamic allocation of IP address services, when a network of more computers, we need to manually set the IP address for each client, subnet mask, DNS and gateway and other addresses, operation is very troublesome. With DHCP we can be a dedicated DHCP server for the client to assign the above network parameter information, so that in the ma
Background: Corporate DHCP server for security, generally at least 2 DHCP server, 1 fault another can work properly. However, 2 DHCP server How to assign the address is a problem, under normal circumstances, DHCP server receives a DHCP request, will send an offer message. Cl
The DHCP lease is divided into the following six processes:1.Client request IP Address:The client sends a DHCP Discover packet in broadcast mode to find the DHCP server. The broadcast contains the MAC and computer names of the DHCP client.2.Server Response:When the DHCP serv
For DHCP servers, we can set multiple hosts. So how can I use a multi-host DHCP server to connect to multiple independent subnets? Next we will mainly explain this problem. 1) use a multi-host DHCP server to connect to multiple independent subnets. /NIC1: 192.168.1.1 --- vswitch group 1 --- subnet 1 DHCP server/ \ NIC2
1. DHCP spoofing attacks 1. a DHCP attacker can also provide SERVER services in a VLAN. 2. DHCP attackers will respond to the DHCP Client's sending request information. 3. attackers will allocate IP addresses and other information and default gateways to DHCP clients. Note:
The use of DHCP is no stranger. So we usually establish a DHCP server in a network. How should we supervise it? In a network using TCP/IP protocol, each computer must have at least one IP address to communicate with other computers. To facilitate unified planning and management of IP addresses in the network, DHCPDynamic Host Configure Protocol and Dynamic Host Configuration Protocol have emerged. This kind

There are two VLANs throughout the network, for a simplified description, assuming that each VLAN has a 24-bit network address, where the IP address of the VLAN1 is 192.168.1.254,vlan2 192.168.2.254.
