    This is what I do if I am changing a handful of IPs:

    [b:ddf58cc138]For httpd.conf:[/b:ddf58cc138]

    # cd /usr/local/apache/conf
    # cp httpd.conf cp httpd.conf.backup [backup httpd.conf]
    # perl -p -i.bu -e &s/xx1.xx1.xx1.xx1/xx2.xx2.xx2.xx2/g;& *.conf [assuming httpd.conf is the only .conf file in that folder; repeat this step for each IP you want to change]
    # rm -Rf *.conf.bu

    xx1.xx1.xx1.xx1 = Old IP address
    xx2.xx2.xx2.xx2 = New IP address

    [b:ddf58cc138]For the zone files:[/b:ddf58cc138]

    # cd /var/named
    # cp -a ./ ../named-backup [backup the named folder]
    # perl -p -i.bu -e &s/xx1.xx1.xx1.xx1/xx2.xx2.xx2.xx2/g;& *.db [Repeat this step for each IP you want to change.]
    # rm -Rf *.db.bu

    It takes just a few seconds to change each IP.
