We’ve been wrestling some networking issues and it seems that DNS may be part of the problem. (I know! Big surprise!). I was reminded of the trusty O’Reilly book “DNS and Bind: Help for System Administators”
While looking for a use copy at Powells, I found a free book “Alternative DNS Servers”.
A quick look at the table of contents shows that this is a generous gift to the Internet. Thanks Jan-Piet Mens!
