5.4. Words of caution

There are some things I should add here. The IP numbers used in the examples above are taken from one of the blocks of 'private nets', i.e., they are not allowed to be used publicly on the Internet. So they are safe to use in an example in a HOWTO. The second thing is the notify no; line. It tells named not to notify its secondary (slave) servers when it has gotten a update to one of its zone files. In BIND-8 the named can notify the other servers listed in NS records in the zone file when a zone is updated. This is handy for ordinary use. But for private experiments with zones this feature should be off --- we don't want the experiment to pollute the Internet do we?

And, of course, this domain is highly bogus, and so are all the addresses in it. For a real example of a real-life domain see the next main-section.
