Warning: Permanently added the RSA host key for IP address

The IP addresses have changed again.

github publishes the list of used IP addresses here so you can check the IP address in your message against github's list:

https://help.github.com/articles/about-github-s-ip-addresses/

Or more precisely:

https://api.github.com/meta

It looks like this (as I write this answer!):

verifiable_password_authentication  true
github_services_sha "4159703d573ee6f602e304ed25b5862463a2c73d"
hooks

2   "18.195.85.27/32"
3   "18.194.104.89/32"

1   "54.166.52.62"
2   "23.20.92.3"

If you are unsure whether your IP address is contained in the above list use an CIDR calculator like http://www.subnet-calculator.com/cidr.php to show the valid IP range.

E. g. for 140.82.112.0/20 the IP range is 140.82.112.0 - 140.82.127.255


Here are the steps that i took to solve the issue and you can try also

  1. Open git bash terminal
  2. type ssh-keygen and hit enter
  3. then terminal will ask to enter the file name to save the rsa key.you can hit enter not
    -typing anything
  4. After that terminal will ask for other information too. without typing anything just hit enter By completing every steps a rsa key will be generate in the mentioned file.
  5. Go to C:\Users\<username>\.ssh and open a file named id_rsa.pub in notepad and copy the key
  6. then go to your github account Settings and select the option SSH and GPS keys .
  7. Create a new ssh key with a title and the key you just copied (you just generated) hit save now if you try to push by git push origin master I hope you wont get any error

If you are accessing your repositories over the SSH protocol, you will receive a warning message each time your client connects to a new IP address for github.com. As long as the IP address from the warning is in the range of IP addresses , you shouldn't be concerned. Specifically, the new addresses that are being added this time are in the range from 192.30.252.0 to 192.30.255.255. The warning message looks like this:
