on OP you ask >>>wildcards for Firewall Address List<<<
not wildcards for DNS static entry, already existent
Again, you not understand.
Actually if I put
www.google.it on firewall address-list it also add one or more dynamic IP with timeout equal as given reply DNS timeout.
If some wildcard are used, just one "dot" for example, routeros, for do what you want, must try all valid dns characters like:
1.google.it, 2.google.it .... a.google.it, b.google.it ... y.google.it, z.google.it
then with one single wildcard characters must do 40 DNS requests.
If added something like "*" wildcard, routeros must try from
1.google.it
to
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz.google.it
for do that, must do (243 positions with 40 possible values each position = 40^253 =) ~ 2*10^405 of DNS querys
Just 2*10^405 of DNS querys, for each wildcard DNS on address list..
Numbers of atoms on the universe are like 10^82...
very feasable, not?
