Anyone got a problem with this? Address books

I have setup my address books as such...

security {
address-book {
MyNetwork {
address MyNetwork {
range-address 192.168.1.2 {
to {
192.168.1.254;
}
}
}
address IPV6-2001 2001:558:5516:37::0/56;
address IPV6-2601 2601:204:ce00:5550::0/62;
address IPV6-fe80 fe80::0/10;
attach {
zone trust;
}
}
global {
address MyNetwork {
range-address 192.168.1.2 {
to {
192.168.1.254;
}
}
}
address IPV6-2001 2001:558:5516:37::0/56;
address IPV6-2601 2601:204:ce00:5550::0/62;
address IPV6-fe80 fe80::0/10;
}
}

Does anyone have something similar with no problems?

Can anyone comment on this. It's more about the global side, but any comments are welcome.

Can anyone report failure in the way of internet connection loss?

All comments welcome.
