ipam

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

the physical NIC on the host to receive the corresponding VLAN. Docker driver specifies Macvlan when creating the network. The Macvlan network of Docker is measured, and the container running on the Macvlan network is 10~15% about the performance loss of the container running in the host network, 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

concepts: Router (Router)A tenant corresponds to a router, connected to the same router bridge network. Midonet will create a privierrouter, all tenants router connected to the Privierrouter and extranet. Equivalent to a router intranet interoperability, connect the superior router access to the public network. Bridge (Bridge)A tenant can have multiple bridges, each with a different network segment. For example, a bridge network segment 192.168.0.0/24 can have up to 253 virtual devices

container network has a double-hung pattern. A CNM architecture led and developed by Docker, and another CNI architecture led by Google, Kubernetes and CoreOS.

This problem allows you to discover new network technology information such as network controller and Generic Routing encapsulation (GRE) tunneling, and new features of existing technologies, including IP address management (IPAM), Dns,dhcp.

mainly implemented by tunneling and routing, one is to packet the basic network protocol, and the other is to configure more complex routing configuration to realize the network communication among the containers across the host. In fact, the above two more or less will give us the implementation of the network to bring complexity and loss of performance, because when we have a large business cluster, these complexity and performance loss can not be ignored. The plugin principle is as follows :

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
