- Introduction
-
- A domain database contains names. These names generally refer to
- either machines part of the domain or sub-domain. This dialog allows
- you to define both.

- You can define up to 4 IP numbers per _D_N_S entry. There is four combo
- box edit fields. A help pop-up is available to help you select one
- available (not already used) IP number. You must have defined your IP
- ranges first using the IIPP aallllooccaattiioonn ssppaaccee menu of the main DDNNSS
- ccoonnffiigguurraattoorr menu.

- A sub-domain is a way to handle authority to another administration.
- Setting a sub-domain involves mostly telling where is the _D_N_Ss
- managing this sub-domain. This is a two steps process. You must first
- define which machines are managing the sub-domain and next, you must
- gives the IP number of those machines if they are part of the sub-
- domain. A _D_N_S of a domain need not be part of the domain it is
- managing.

- Some facts first...
-
- ╖ This machine is the _D_N_S of foo.com.
-
- ╖ You want to create the sub-domain sub.foo.com.
-
- ╖ The primary _D_N_S of the sub-domain will be dns.sub.foo.com.
-
- ╖ The secondary _D_N_S of the sub-domain will be ftp.sub.foo.com.
-
- You do...
-
- ╖ Edit the record sub.foo.com (It is new).
-
- ╖ Under the section DDNNSS aaddvveerrttiissiinngg enter dns.sub.foo.com and
- ftp.sub.foo.com.
-
- ╖ Edit the record dns.sub.foo.com and set the IP number(s) of this
- machine.
-
- ╖ Repeat the operation for ftp.sub.foo.com.
-
- Now your _D_N_S knows two things: Which machine(s) is(are) responsible
- for the sub-domain sub.foo.com, and, how to reach it. This
- information combination is often refer-ed to as the _g_l_u_e _r_e_c_o_r_d.
-

-
- It is not necessary to setup a complete sub-domain just to have a sub-
- category of machine. Suppose that for a project, you want to refer to
- two machines as ftp.project.foo.com and www.project.foo.com, you can
- simply defines theses machines IP using the hhoosstt iinnffoorrmmaattiioonn screen.
- The information will be dispatched in the ffoooo..ccoomm database.
- 33.. EEmmaaiill aaddvveerrttiissiinngg
-
- It is sometime needed to redirect the email traffic for a host or
- domain to a specific email server. This is often done "domain wise" in
- the pprriimmaarryy ssppeecciiffiiccaattiioonn screen of a domain.
-
- It is sometime necessary to do an exception for either one machine or
- a sub-domain. You can do this here and specify up to three email
- servers.
-
- 44.. DDeelleettiinngg oonnee _D_N_S eennttrryy
-
- The button DDeell of the dialog is used to delete this record from the
- DNS. A confirmation pop-up will let you confirm (or not) the deletion.
-
- Deleting such a record will cleanup both the domain database and the
- reverse mapping.
