If that's the correct file that BIND is reading, then:

(1) make the necessary changes to the A and PTR records

(2) Change the serial number in the file
    (typically date plus an ordinal, so something like 2008120801)

(3) Restart BIND, or just instruct it to reload the zone using rndc
    (most basic form:  rndc reload, but see rndc.8)
