In Windows Server 2012, there is a new feature: IP address management, referred to as ipam (IP addresses Management), with the increase of DNS and DHCP servers in the enterprise, although the graphical interface allows us to easily manage, however, As servers become more and more likely to be dispersed in different divisions or regions, if we can take advantage of Ipam's management tool, we can reduce our administrative burden and monitor our services

If your company still uses workbooks to manage tens of thousands of IP addresses, pay attention to the fact that many smart engineers have begun purchasing IP Address Management (IPAM) solutions. This seems strange, but IPAM and IPv6 projects have many things in common-they are both essential, but they are not a high-priority IT job. However, there are also differences: the advantages of IPv6 cannot offset

, but the overall performance is stable and there is no jitter. This is acceptable. Based on Macvlan, we developed our own Ipam Driver plugin-based on consul. When Docker creates a Macvlan network, it drives a consul that is designated for its own development. The IP of free and used is recorded in the consul. Such as: The IPAM driver is present on each host and is exposed to the Docker call via the socke

This thing Stone Age network model, basically cannot be adopted by enterprise.Later evolved to the next stage, we call it the hero of the solution, very good, such as rancher IPSec-based network implementation, such as flannel based on the three-tier routing network implementation, including our domestic also have s

Host Let's take a closer look at the details of the three networks:The name is network, and the user can define it arbitrarily.IDs are network internal UUID, globally unique.Scope currently has two values "local", "remote", indicating whether it is a native network or a multiple-machine network.Driver refers to the name of network driver.Ipam is the driver name and configuration information (which we can see in the Bridge Network) for IP management issues.Information about cont

; This IP address management is not unique to the container, the traditional network such as DHCP is actually a IPAM, to the container time we talk about IPAM, the mainstream of two methods: based on CIDR IP address segment allocation or accurate for each of the containers assigned IP. But in short, once a container host cluster is formed, the above container assigns it a globally unique IP address, which i

In many cases within the enterprise, you will encounter the following events: 1. Need to track the use of the overall IP address space; 2. Need to be urgently aware of which address is idle for quick allocation to a new device or a DNS SRV record; 3. When the address range of the DHCP server is exhausted, it is expected to have an emergency address space; 4. If you change some of the parameter options on the DHCP server (such as proxy server), I hope to be able to apply it to all servers as
