- IP range definitions
- Introduction
-
- A _D_N_S manages a bunch of relations between names and IP numbers.
- Every time one adds a new definition to the _D_N_S (a new machine), he
- has to find an unused IP number. Further, it has to get some good
- knowledge of the network to know which one to use. A common practice
- is to document the general organization of the network, associating IP
- numbers range to logical part of the network. _L_i_n_u_x_c_o_n_f allows you to
- enter this information here and will use later, making DNS management
- much nicer.

- You can define as many IP ranges a you needed. An IP range has the
- form ssttaarrtt--lliimmiitt. Here are some IP ranges for different network types.
-
- 119922..116688..11..11--2211
- This defines the first 21 IP numbers of the _c_l_a_s_s _C network
- 192.168.1.0.
-
- 117722..1166..00..11--22..225544gg
- This defines a huge range in a _c_l_a_s_s _B network. Note that this
- notation won't be used much. This kind of network is often split
- into several physical networks, so IP number are allocated.
- This is one place where the "IP range definitions" system is
- very useful.

-
- For each IP range, you must define a comment clearly identifying the
- range later.

-
- At first there is room only for one IP range (and one comment) in the
- dialog. Using the button add will expand the dialog, each time
- allowing one more range. There is no practical know limit to this.

-
- Just erase the content of the two lines defining the range (the range
- itself and the comment) and use the _A_c_c_e_p_t button.

-
- After setting up you IP ranges, you can go to the AAdddd//EEddiitt hhoosstt
- iinnffoorrmmaattiioonn menu. Every time you edit one DNS entry, _L_i_n_u_x_c_o_n_f will
- compute the first available IP number for each IP range definition.
- These IP number will be put in the combo box edit field. You will be
- able to pick an available IP number without guessing from now on.
