Well, kudos to ISP's that do it right. My experience is that
most of them are not nearly as responsible. None of the last
three ISP's I have used at home (all in the U.S. top ten) even
provided NTP servers, let alone served them up in DHCP options.
Of course, none of the last 4 routers I used would have done
anything with them if they had.
