DNS sub-domain best practice
My employer (part of a large educational institution) is delegated a bunch of 4LD zones within our org's 3LD space. These are utilised in a flat fashion, with staff machines, lab machines and servers all present as hosts inside various 4LDs. One 4LD has literally thousands of For obvious reasons, I'd like to move at least some stuff into 5LD space, starting with the labs. However, when I suggested this, my boss shot me down with "Too much typing. If it's a problem then we should differentiate at the 4th level." The only way to deal with that kind of attitude would appear to be a formal proposal (there are other issues in our DNS that need to be tidied up, so it's not just a proposal for this one thing), and I want to include some industry references about best practice in zone structuring. However, Google's not being kind to me at present. All it wants to tell me about is AD and MS DNS, and we're using bind so that doesn't translate so well. Anyone got some guides that I can refer to when I talk about why we shouldn't be using the 4LD as our functional level for all things? -- ËMatthew Poole "Don't use force. Get a bigger hammer."

Very simple, from RFC1034 (http://www.ietf.org/rfc/rfc1034.txt) 8<------------------------------------------------------------------ The result was several ideas about name spaces and their management [IEN-116, RFC-799, RFC-819, RFC-830]. The proposals varied, but a common thread was the idea of a hierarchical name space, with the hierarchy roughly corresponding to organizational structure, and names using "." as the character to mark the boundary between hierarchy levels. ------------------------------------------------------------------>8 And that is all there is to it. Having a 'couple of thousand' hosts in a domain doesn't really matter, that is personal preference if the admin likes it or not, but you can make a case about hierarchy. eg using 'hostname.room.bld.dept.org.tld', though you can also use 'host-room-bld.dept.org.tld'. Thus as with the latter example, you could still resolve this by simply using '-' as a separator instead, happy you, happy them ;) Greets, Jeroen
