This Open Source Guide is about DNS and (mostly) BIND 9.x on Linux (Fedora Core), BSD's (FreeBSD, OpenBSD and NetBSD) and Windows (Win 2K, XP, Server 2003). It is meant for newbies, Rocket Scientist wannabees and anyone in between.
Apparently a single missing full stop at the end of the code meant that the Domain Name Systems (DNS) failed to recognise .se as the “top-level" (country-wide) domain.
