Probably ISC's new packages have installed a "Software Collection" to avoid 
conflicts with "native" packages. Read the scl(1) manual page for more 
information. To get a shell with the proper context to manage named, you'll 
need to run something like `scl enable isc-bind bash`. Or to run ad hoc 
commands, `scl enable isc-bind -- named -V`, etc.. And as you noticed, named's 
configuration and data are now under /opt/isc/isc-bind/.
