![]() This topic describes how to customize networking for Tanzu Kubernetes (workload) clusters, including using a cluster network interface (CNI) other than the default Antrea, and supporting publicly-routable, no-NAT IP addresses for workload clusters on vSphere with VMware NSX networking. At the prompt, type ipconfig and then press Enter.Customize Tanzu Kubernetes Cluster Networking.Open the Start Menu and search for CMD, then open the Command Prompt entry when it appears.If you’re connected to the router using a Windows computer, you can also easily find it using the Command Prompt: Speaking of the user manual, if you’ve lost yours, then it’s likely there’s a PDF version of it on the manufacturer’s website. You can usually also find the same information in the user manual. If you’ve typed 19.168.0.1 into your browser and didn’t arrive at the router’s login page, how can you figure out which address your router uses? There are several fast and easy ways to find out.įirst, most routers have a sticker somewhere with the IP address and the default username and password. Virtually all home routers use either a .x or 10.x.x.x IP address. Other alternatives may include 10.0.0.1, which is from the Class B private IP range. So your router might use (for example) 192.168.1.1. Some alternative addresses are still within the same private IP range. You’ve probably used a router that doesn’t use 192.168.0.1, and that’s completely normal! Since these are private IP addresses, it doesn’t matter which private IP range the router manufacturer decides to use. However, that address is from the so-called “special IP” range, not the private IP range. The range starts at 192.168.0.0 and goes up to 192.168.255.255.ġ27.0.0.1 or localhost is also from the reserved IP ranges for Class C networks. That’s the class for small local area networks (LANs). ![]() The 192.168.0.1 comes from the private IP range of Class C networks. Only Classes A, B and C have private IP address ranges that are reserved for internal network use, not facing the internet at large. There are five classes of IP address range, going from A to E. To ensure that IP addresses are used efficiently, ranges of them are reserved for different uses. ![]() Like a combination lock, there are only a limited number of unique IPs for use on the internet. That’s all good and well, but why 192.168.0.1 in particular? The exact reason is complicated, but the most crucial explanation is that internet IP addresses are limited. So if a laptop on 192.168.0.2 requested data from a website, that would have been noted in the record and sent to the correct private IP address. When routing packets arrive at their public IP address, the router uses a Network Address Translation (NAT) table to record which local device the packet is meant for. So, if all of your devices are connected to the router but only have one public IP address, how does it know which device on the local network should get which packet? That’s the entire purpose of a router, to make sure that packets are routed to the correct place. It may change every time your internet connection disconnects or, if you pay for the privilege, you can get a static IP address that never changes. Your Internet Service Provider (ISP) assigns the public IP address and usually, you don’t have any control over it. This is one of the reasons you don’t want just anyone using your internet connection! After all, your location and identity are tied to your public IP address. ![]() This means that all devices in your home share the same IP address on the internet. ![]()
