Now my pet peeve time. This file: http://www.internic.net/domain/named.root indicates the named.root file should be available at ftp.internic.net or rs.internic.net. It's only at ftp.internic.net. This page has a pointer to root hints file(via FTP) that does not work either. The http version shows the above mistake.

Automation is > good :-) Well, I'm not authoritative, but I don't have a root hints file on my systems. Instead I rely on the hints built in to named, which get updated when I update BIND. Also it doesn't matter if the hints are out of date since the root name server list changes very infrequently and you only need one of them to work for named to start OK.

RE: Root hints updates
>> Since the first thing BIND does at startup is to check the root NS set, and since DNSSEC guarantees that it is genuine, is there still an use for this tool? Unless bind updates the hint file as a result of these checks, yes. It's not a question of authenticity; named has to start somewhere to find the root NS; this is the bootstrap cache. It wouldn't be a bad thing if bind did the update itself (sort of like DNSSECS's 5011 for keys). But so far as I know, it doesn't. Since I run the tool, I can't say that I've ever seen a message from BIND complaining about the root hints being out of date. I know there was a root hints update last June... Does it sync to what it finds, or just complain? Until someone authoritative tells me that BIND manages the hints file on its own, I'm taking the conservative route and letting my tool run BTW, I do have systems that come on-line every 5 years or so.
