<div dir="ltr">I know this may sound a little odd, but have been struggling with trying to identify a good candidate for a DNS (& DHCP) migration of a large infrastructure, from Windows based environment, to a vendor based appliance (and keeping such as a full time employee, in the process, in the network group, for administration and lifecycle of such). <div>
<br></div><div>I would think that primordial to a level of strong engineering abilities would be networking (TCP/[UDP]/IP on top of which DNS as protocol and its behaviors knowledge would be a must). The OS level knowledge comes next, as bind on *nix or on F5 (thinking GTM here), for example, needs to be comprehensively understood, as well as the Windows implementation and relationship between DNS and AD. Security comes as a "given", of course, as name resolution is critical from that stand point, especially on the public facing part. Vendor "X" appliance background is also desirable, on top of all these, 'cause that would be the "moving to" point, and understanding specifics will be critical. Add to this knowledge of applications and possible name resolution specifics at layer 7, maybe not following the "rules" of the OS stubs, and I pretty much covered the entire computer science spectrum ;-)<div>
<br></div><div>Considering all of the above - what is your experience and/or opinion in regards to how a good DNS engineer (or a good engineer with primary responsibility in another technology) came to become? What helped you the most in becoming one?<br clear="all">
