To clarify:

The distinguished gentleman from RIPE is also correct.  Once BIND
starts, IF any of the built-in root name servers is correct [very likely
on the public Internet, unlikely on any other internet], it will get the
complete current list, as this should be identical on all root name

But the answer to your original question remains, "no" - it does not
do a file transfer to download any file to keep its boot-time root hints
list persistently "current".

[This does leave a security hole - if a root name server's IP changes,
and a Bad Guy gets the old one; or on another internet, if the Bad Guy
gets all the IP addresses in the default file.  It's not just lust for
control that has me using a visible root hints file.]
