You can update all your DNS zones at once using a simple
replace command executed from the shell as root:
Code:
# cd /var/named
# replace 'someuser.domain.com' 'newuser.newdomain.com' -- *.db
# service named restart
In the above example illustration, you would just replace
someuser.domain.com
with your old SOA contact email address and
newuser.newdomain.com
with your new SOA contact address
(
NOTE: Email addresses in zone files are stored with a period (.) replacing
the normal AT (@) symbol you normally see in email addresses so the
email address 'user@domain.com' would actually be 'user.domain.com')
