How to set ipWhitelist for all device can acess to MagicMirror v2?

AAPS

If having “/24” in my ipWhitelist works, should it be fine without changing to “/120” ? This has been confusing me lately, so any help would be appreciated.

@Mykle1 Glad it all worked out!

@AAPS Theoretically you are fine but you are whitelisting a lot of IPs. Assuming you are talking about IPv6. Here is a brief explanation example:

192.168.1.1/24 subnet mask on IPv4 network would cover IP 256 IP addresses ranging from 192.168.1.0 to 192.168.1.255.

Start IP: 192.168.1.0
End IP: 192.168.1.255
Addresses: 256
Class: Class C
Netmask: 255.255.255.0.
Binary: 11111111	11111111	11111111	00000000

::ffff:192.168.1.1/120 subnet mask on IPv6 network would also cover 256 IP addresses

Start Range: 0:0:0:0:0:ffff:c0a8:100 (IPv4 equivalent of 192.168.1.0)
End Range: 0:0:0:0:0:ffff:c0a8:1ff (IPv4 equivalent of 192.168.1.255)
Addresses: 256

Now if you have ::ffff:192.168.1.1/24 subnet mask on IPv6 network, you would allow 20282409603651670423947251286016 IPs to access your mirror. Which seems to be alot, but remember that devices most likely have to be on your home network in the first place.

Start Range: 0:0:0:0:0:0:0:0
End Range: 0:ff:ffff:ffff:ffff:ffff:ffff:ffff
Addresses: 20282409603651670423947251286016

Hope this helps.

I seem to be fine, but do you recommend that I change anyway?

@AAPS It’s totally your call. I don’t think it affects anything as long as your network is closed and secure.

@morozgrafix Thanks! I am pretty late, but congrats to you and all the other new moderators.
