I read a story about a company bringing DNS management "in house"  I never heard of this!   What advantage is there for a company/organization to bring DNS "in house"

Question 2:  is INFOBLOX used for this type of organizational initiative?

It depends if you mean external DNS or internal DNS??

Many organizations use split-DNS if their internal and external DNS zones are the same, but managing their own external DNS records in-house is not something that most would want to do as it would mean that their web-facing services rely on their own internet circuits being available, even if services are hosted elsewhere, for example.

Are you sure they are not using something like OpenDNS to handle the management of the DNS? As outlined by Craig I wouldn't recommend in house management of external DNS either, we usually use OpenDNS and NO-IP.

I worked at a large College where we ran our own external DNS, but used our ISP to provide secondary failover in the event of our DNS server going down.

Now I work at a larger institution and we let our ISP host it entirely - we just make changes via a web front end. It's far easier.

Question:  The decision to take external DNS over and manage it internally has to do with auto-failover of email and host names.  Can anyone explain this?

Autofailover of email is done with MX records.

Autofailover of hostnames is only achievable using DNS round-robin.

Both of which can be done with internal or external DNS.

Network solutions has gone down in the past and in this case multiple MX records don't seem to matter.
