If you want to be a network administrator, you have to know the DHCP protocol. This Protocol plays an important role in network address management. Next we will explain some concepts of this Protocol. We hope you will gain some benefits.

DHCP DHCP is the abbreviation of Dynamic Host Configuration Protocol (Dynamic Host Allocation Protocol). Its predecessor is BOOTP. BOOTP was originally used on a network without a disk host connection: the network host uses boot Rom instead of the disk to start and connect to the network. BOOTP can automatically set the TCP/IP environment for those hosts

second reply is usually ignored.To resolve this issue, either make sure that the router has a secure path to the DNS server, or do not use DNS, and use manual parsing. With manual resolution, you can turn off DNS, and then use the IP Host command to statically define the host name. If you want to prevent the router from generating DNS queries, either configure a specific DNS server (IP name-server), or use these queries as local broadcasts (when the DNS server is not configured), using the foll

, and the IP address should meet the requirements. If you use the static IP Address Setting method, you will still encounter difficulties in allocating addresses, because the computer uses random IP addresses, and no matter how the address is allocated, conflicts cannot be avoided, DHCP can avoid this problem. DHCP can also be used to set other IP settings, such as default routes and DNS servers, to reduce the management tasks of a large network. DHCP is developed from the original

network management end to implement centralized IP management. The solution is to use DHCP. 　2 main DHCP Functions DHCP stands for the Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol), designed by the IETF (Internet network engineer Task Team). The detailed Protocol content is in RFC documents rfc2131 and rfc1541. The objective is to reduce the planning, management, and maintenance burden of TCP/IP networks and solve the problem of insufficient IP address space. The ser

　　 What is DHCP? DHCP is the Dynamic Host Configuration Protocol (Dynamics host Configuration Protocol), which is designed to reduce the burden of planning, management, and maintenance of TCP/IP networks and to address the lack of address space. This kind of network service facilitates the effective management of the client IP address in the network. The DHCP feature is divided into two parts: one is the server side and the other is the client (the client does not have to install, a

DHCP is the acronym for Dynamic Host Configuration Protocol, which is formerly a BOOTP. BOOTP was originally used for diskless host-connected networks: Network hosts use the BOOT ROM instead of disk to start and connect to the Internet, BOOTP can automatically set the TCP/IP environment for those hosts. But BOOTP has a

You only need to remember the domain name to quickly access the website.Port Vulnerability: If the DNS service is enabled, hackers can analyze the DNS server to directly obtain the IP addresses of hosts such as web servers, and use port 53 to break through some unstable firewalls to launch attacks. Recently, a U.S. company also announced 10 most vulnerable vulnerabi

Networks can be divided into LAN and WAN. Here we will talk about the content of the lan dhcp protocol. Including its conceptual structure and some IP Address Allocation content.

I believe you have a preliminary understanding of the use of the DHCP server. Therefore, we need to study this part in depth. This time, let's talk about BOOTP/DHCP Relay Agents. Next let's take a look at the specific introduction. If you need to create multiple DHCP servers, but the DHCP server and the client are located in different network segments, your IP Router must comply with RFC1542, DHCP/BOOTP Rel

DHCP protocol is widely used, which is especially important for LAN. Here we will explain the management content. For many servers, the related knowledge also needs to be mastered by administrators. So here we will explain the DHCP from the basic aspect.

If the file can be written by the client, the TFTP server returns an ACK packet with the block number 0, and the client sends the first 512 bytes of the file with the block number 1. The server returns the ACK with the block number 1.The data transmission of this protocol is called the Stop wait protocol.The last TFTP packet type is error packets. It is use
