networking - Why is localhost IP 127. 0. 0. 1? - Super User 127 is the last network number in a class A network with a subnet mask of 255 0 0 0 127 0 0 1 is the first assignable address in the subnet 127 0 0 0 cannot be used because that would be the wire number But using any other numbers for the host portion should work fine and revert to using 127 0 0 1 You can try it yourself by pinging 127 1 1 1 if you'd like Why they waited until the last
Whats a loopback-address? I. e. 127. 0. 0. 1 - Super User What is a loop-back address? 127 0 0 1 is a loop-back address, but what does this even mean? Please be very descriptive and give an example, as I'm having a hard-time understanding this
Proxy http: 127. 0. 0. 1 through Proxy Server in Edge, IE11 or IE10 I can, but what is important is that all of my apps I'm working on (10+) require the host to be 127 0 0 1 And that, unfortunatelly, cannot be done by using hosts file redirection That would require re-configuring every single app to use 'localhost', or some other domain instead, which is just too much work for every developer in my team (they will be using that same solution as well)
I can not access http: localhost but http: 127. 0. 0. 1 works fine Mine is Ubuntu 20 04 VM I had this following line ::1 localhost ip6-localhost ip6-loopback I commented that line and added the following line ::1 ip6-localhost ip6-loopback Basically removed ::1 localhost It now works The final look of the hosts file is as follows 127 0 0 1 localhost 127 0 1 1 vagrant vm vagrant # The following lines are desirable for IPv6 capable hosts #::1 localhost ip6
What is the 127. 0. 0. 2 IP address for? - Super User The Wikipedia page has since changed, and now says "although any address in the range 127 0 0 1 to 127 255 255 254 is mapped to it", rendering the gist of this answer in direct conflict with Wikipedia
Cant access the 127. 0. 0. 1:8888 port - Cloudera Community I just set up my VM and am taking a hadoop course but cannot access the 127 0 0 1:8888 address on my browser Do you have any recommendation to fix this error? Here's my screen shot when I turn my VM on thanks for your help!
cant access 127. 0. 0. 1:80 outside of WSL2 Ubuntu 20. 04 That's because each host has a localhost 127 0 0 1 The windows host thinks it's going to itself The easiest solution is for you to IP with a real IP example 192 168 x x I found the following blurb In the early stages of WSL 2, we can’t use localhost We need to use an IP since Linux is inside a VM To access your application currently, we will use an IP
http: localhost:3000 works, but http: 127. 0. 0. 1:3000 doesnt In your hosts file, you have both a IPv4 and a IPv6 resolution Most operating systems today will prefer IPv6 if available Since localhost is working and 127 0 0 1 is not, this could be your problem There are two things I would check in this case: Check to see if the server service is running only on IPv6 If so, change it so it is running on both IPv4 and IPv6 Check the firewall rules to
