I said that when any program ( like php etc) run over localhost address then it is not visible over public ip. IP address 127.0.0.1 is a Private or Reserved IP of type IPv4. In php, they say to use 0.0.0.0 for public and 127.0.0.1 for local You give me a Good reason for this i Appreciate itīut your reason in only valid over php. You can also host your PHP application on Azure App Service. If you publish your PHP application on a public network, we recommend hosting it with Apache or Nginx and controlling the communication with a virtual network or firewall. If you want to keep your Azure virtual network private, don't give it a public IP address. The built-in Web Server should not be used on a public network.įrom here, I will talk about what you can do with Azure.
You should not use it on public networks. The PHP documentation also notes the following: This is a PHP built-in web server specification, not an Azure issue. Localhost is often considered synonymous with the IP address 127.0.0.1. To make NGINX listen to all 3 of the interfaces, we can bind it to interface 0.0.0.0 using the same listen directive: listen 0.0.0.0:80 3.2.If 0.0.0.0 is specified, it can be accessed from any remote server.
This means the NGINX process will not accept packets coming from the other 2 interfaces: enps03 and docker0. With this configuration in place, the NGINX will listen on port 80 of the loopback interface. Then, we configure the NGINX with the listen 127.0.0.1 directive: listen 127.0.0.1:80 Specifically, we have a loopback interface lo, an ethernet interface enp0s3, and a virtual interface for Docker docker0. Inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0įrom the output, we can see that there are 3 interfaces available in the system. This is ordinarily implemented using only 127.0.0.1/32 for loopback, but no addresses within this. A datagram sent by a higher level protocol to an address anywhere within this block should loop back inside the host. 127.0.0.0/8 - This block is assigned for use as the Internet host loopback address.

One of the lesser-known IP addresses you should know is 127.0.0.1, but what does it connect to and when should you use it Let's explore what 127.0.0.1 is, and what it can do. Valid_lft 86258sec preferred_lft 86258sec There are a few IP addresses that are useful to know off by hand-your router's IP, for example. Inet 10.0.2.15/24 brd 10.0.2.255 scope global dynamic noprefixroute enp0s3 127.0.0.1 is normally the IP address assigned to the 'loopback' or local-only interface. Link/ether 08:00:27:a9:1b:40 brd ff:ff:ff:ff:ff:ff IP address is used in all personal computer but it never let them to communicate with other devices like the original IP address. Step 2 Follow the points discussed in the Internet Explorer section.
