wellsfargo.com has 151.151.0.0/16 at least.. probably more. You really
think you can trust 65534 hosts, so long as somebody setup the DNS
properly?
IMO, you can't/shouldn't trust any host you don't directly control.
Everyone else either IS an adversary, or is vulnerable to being
manipulated by an adversary. That may seem a little paranoid, but it
has served me well over the years.
They don't get into my trusted networks, and I'm surely not going to put
them into my whitelists, nor trust hosts just because they got put into
a global whitelist.
