You were responding to someone who offered a /24 as a subnet.
There are 32 bits in an IPv4 address. /24 is 255.255.255.0.
So they were wrong too in reference to IPv6, but at least they were making sense.
You responded with /128, which is the full range of the IPv6 address.
That would be like the prior poster saying /32 aka 255.255.255.255.
There’s no usable range there.
And, see my post above for the rest of the breakdown, but you were looking for /64.
/128um … that’s wrong.
why?
Two reasons.

But the mask is a firewall to prevent viruses from leaving or reaching you, so a firewall on ::1/128
Ah. Well that’s nonsense, but it is a take on the graphic with some internal cohesion.
