That’s a lot of “Who and where is this address,” requests!

• Speaking of DNS, we have started the process of presenting a unified internal view between the Medical Center and the University.  This will help clients in both institutions ti be resolvable within the Vanderbilt community.  In regards to email, this will go a long way to help us secure the environment and streamline our processes.  Initial testing has been successful and a roll out into production is scheduled for mid-September.

• The DNS servers were successfully patched to address CERT Vulnerability Note VU#725188.  There was no interruption of service to the community.

• 2 additional departments have been tapped for Self-Serve DNS/IPAM and will receive their training from ITS in the first week of September.  This is a part of the ongoing plan to empower selected departments to administer their own DNS and IP space while alleviating some of the load on ITS.

• DHCP migrations off the old NetID environment continue to be on pace with an earlier than expected completion.  We are currently at 66% of migrations completed with little impact to the customer base.

• The ESX environment will receive a nice boost in capability at the end of August with the addition of 8 more cores and 256GB of RAM.  The ESX development environment is slated for replacement with the current assets being redistributed to help out other production clusters.  This is an ongoing effort to increase our virtual hosting capacity and improve efficiencies.
