<p><span lang="EN-AU">Circa 2008 two named servers were handing 50k+ ADSL customers, load shared by alternating anycast DNS server addresses on a per- BRAS bases. That included a view selected based on source address, which may increase processing load over
a vanilla named configuration.</span><o:p></o:p></p>
