| # Fixed IP addresses can also be specified for hosts. These addresses |
| # should not also be listed as being available for dynamic assignment. |
| # Hosts for which fixed IP addresses have been specified can boot using |
| # BOOTP or DHCP. Hosts for which no fixed address is specified can only |
| # be booted with DHCP, unless there is an address range on the subnet |
| # to which a BOOTP client is connected which has the dynamic-bootp flag |

| # You can declare a class of clients and then do address allocation |
| # based on that. The example below shows a case where all clients |

| # other clients get addresses on the 10.0.29/24 subnet. |
