What is localhost:8080 ?

Everything connected to the internet can be found using a socket address. socket Addresses are a combination of IP addresses ( or simply hostname ) and port numbers. socket Addresses are used to identify both machine and the overhaul within the machine. If we consider localhost:8080 then here localhost is hostname which is bound to IP address i. 127.0.0.1 by default and 8080 is the larboard. here, localhost means this computer i. the computer which you are using right now. fig. socket address is a combination of a hostname(or IP address) and port number Ip address is precisely like family savoir-faire which finds the right house. similarly, Ip finds a particular system in a network. Port is the person number. Person number which finds an actual person on that house. similarly, Post used to identify the summons that needs to consume the mailboat. In localhost:8080, localhost is DNS hostname which is pointing to localhost IP cover i. 127.0.0.1. If you type ping localhost in terminal or instruction immediate, you will find that your machine automatically points localhost to IP addresses such as :1 or 127.0.0.1. actually, 127.0.0.1 is the IPV4 cover and : :1 is the IPV4 savoir-faire of localhost.So typing localhost:8080 or 127:0:0:1::8080 are lapp things. here 127:0:0:1 is a individual Ip address that is not recognizable by another computer in the net. It is recognized by this machine alone. by and large while building the application locally by the network developer, they develop the web application and the default socket will be localhost:8080. This is the default interface that the webserver XAMP, WAMP, LAMP server uses for developing and testing the application.8080 is precisely a random port person sets in different web servers for testing and development and you can change it if you want. But note that no two applications or processes can use the lapp interface. internet explorer. two applications running can not run on port 8080 at the same time. If one process is using 8080 then if another application tries to access 8080 then it will give you a message like “ port is already in used “ please use another port. If you are running a .net application or PHP application and when you are debugging that application it will have localhost:8080 upon running in the browser URL by default. The webserver will not search the information on the internet but will search pages in a local hard drive it will search for the web page by local webserver at port 8080 from the local hard campaign If you are using a window machine, then the IIS server is enabled then good typing localhost will redirect you to C : /inetpub/wwwroot/iisstart.htm files. here the port by default is 80. Considering C driveway is your bone drive. similarly, if you use the XAMP server then typing localhost will equitable find the content like index.html or index.php salute in htdocs folder. url Syntax : { scheme } : // { hostname } : { port } { path } then for localhost:8080, { dodge } is “ hypertext transfer protocol ”, { hostname } is “ localhost ”, { port } is 8080 and { path } is “ / ”

What is 8080 port?

It is to be noted that there is a entire of 65,535 ports for communication between the devices where 0-1023 are well-known reserved ports you can not assign IP to this. Port 1024 to 49151 are user ports and users can assign applications to them. And port above 49151 is a private port. so, port 8080 is the user registered port. In our case by default XAMP or WAMP server impute for the application. If you have a web server already running on default port 80 and you like to host another vane server on the HTTP serve then the webserver will automatically host you to port 8080 which is a best practice followed by most of the vane servers and if that port is besides in use then may assign any exploiter interface like 8081,8082 etc

You can change it, the only thing you have to keep in mind is that you can not assign an already used port differently it will give an error as we have mentioned earlier 8080 must be explicitly specified for HTTP as 80 will be assumed by most browsers. But some web server like Angular, Rails server uses 8000, 4200 as the default port

What exactly is going on When I type localhost:8080?

Ans : When you type localhost:8080, this will make your web browser ask your operate system to do a DNS search and resolve the hostname as localhost. The function system looks at the files for DNS search. In the windows system, the DNS map is located inside the hosts file located inside % systemroot % \System32\Drivers\Etc path and the hosts file look like this :

127.0.0.1       localhost
 ::1                 localhost

figure. localhost map to 127.0.0.1 In Unix systems like Linux, the DNS map are stored inside /etc/hosts file, and look like this :

127.0.0.1   localhost
::1     localhost ip6-localhost ip6-loopback

fig. mapping localhost to 127.0.0.1

so when you hit localhost:8080 the browser then the webserver finally gets the solution from the 127.0.0.0:8080 location and displays the leave in the browser. Conclusion: When you run a web server on your local calculator, you will have to connect a web application with the webserver and port 80 is already in practice, so you will need to use a new port. so, most of the web server usage available port 8080 to connect application which is presently running. If larboard 8080 is already in manipulation by some other march then the web server may assign 8081 for the lotion .
