All my IPv4 addresses come from [4]bytes that I previously converted into
net.IP.
So all my IP are classic IPv4 and not IPv4-mapped into IPv6 address (as
describe into https://tools.ietf.org/html/rfc3493#section-3.7)

Thx again for this complement.

using that as a map key is risky business if you don't know how the
net.IP came to be. You're depending on it's internal representation
and there's more than one way it can express the same IP.

As net.IP is []byte, does the compiler implement the same optimization when
you do this :
var m map[string]string
val, ok := m[string(net.IPv4zero)]
While not what you're asking, note that doing string(someNetIP) andyou do this :
var m map[string]string
val, ok := m[string(net.IPv4zero)]
using that as a map key is risky business if you don't know how the
net.IP came to be. You're depending on it's internal representation
and there's more than one way it can express the same IP.
