```bash
[DEFAULT]
ignoreip = 127.0.0.1/8 XXX.XXX.XXX.XXX #<= the IP address (you can put more than one, separated by a space) that you want to whitelist
ignoreip = 127.0.0.1/8 XXX.XXX.XXX.XXX ; <= the IP address (you can put more than one, separated by a space) that you want to whitelist

```bash
[DEFAULT]
ignoreip = 127.0.0.1/8 203.0.113.4 2001:DB8::1
```
5. Save the file and reload the Fail2Ban configuration:
```bash
sudo fail2ban-client reload
```
6. Check that the configuration has been applied as expected:
1. You should have this result
```bash
root@sambain:/etc/nginx# fail2ban-client get sshd ignoreip
These IP addresses/networks are ignored:
|- 127.0.0.0/8
|- 2001:db8::1
|- XXX.XXX.XXX.XXX
`- 203.0.113.4
```
2. If there is an error with your change, you could end up with something like this:
```bash
sudo fail2ban-client get sshd ignoreip
These IP addresses/networks are ignored:
|- 127.0.0.0/8
|- #<=
|- the
|- IP
|- address
|- (you
|- can
|- put
|- more
|- than
|- one
|- separated
|- by
|- a
|- space)
|- that
|- you
|- want
|- to
|- whitelist
|- 203.0.113.4
|- XXX.XXX.XXX.XXX
`- 2001:db8::1
```
