== Updating the root.hints file with dig ==
Instead of downloading https://www.internic.net/domain/named.root, you can run:
{{{
dig @a.root-servers.net  .  ns > db.cache
grep '^\.\|^[a-z]' db.cache | sort >/srv/named/etc/namedb/root.hints
}}}

That will give you a file very close to the BLFS example.
Sanitized so no leading spaces are introduced.

== Verifying the tarball using gpg ==
You may want to verify the validity of the downloaded files from
isc instead of trusting the MD5 from the book.[[BR]]
Run these commands if you have gpg installed:
{{{
wget https://www.isc.org/docs/isc-keyblock.asc
gpg --import isc-keyblock.asc
wget https://downloads.isc.org/isc/bind9/<version>/bind-<version>.tar.xz{,.asc}
gpg --verify bind-<version>.tar.xz.asc
}}}
