<p class="MsoNormal"> Our normal procedure when changing the IP address of a TLD name server is to get the new server responding properly and then update the glue records with the Registrar to reflect the new address, normally 1-2 days apart
for two nameservers. We monitor query traffic on each and usually see a distinctive shift once the glue record is updated and almost all traffic shifts in the first 24 hours. e.g.<br>

<o:p></o:p></p>
<p class="MsoNormal"> ns1.example .com – 1.2.3.4 (first day) <span style="font-family:Wingdings">
à</span> 10.20.30.40 (confirm normal ops)<o:p></o:p></p>
<p class="MsoNormal"> ns2.example.com—5.6.7.8 (second day) <span style="font-family:Wingdings">
à</span> 50.60.70.80<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> We had someone on staff make a suggestion we could modify this approach by adding an additional IP address for each of the existing servers:<o:p></o:p></p>
<p class="MsoNormal"> ns1.example.dom – 1.2.3.4 (first day) <span style="font-family:Wingdings">
à</span> 1.2.3.4 & 10.20.30.40 (confirm normal ops)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> I never even thought a Registrar would allow this? Is it supported? A useful idea in certain scenarios (although I’m not sure when) ?<o:p></o:p></p>
