配置文件详解：
#This file should be in the same folder where DualServer.exe file is.
#Any entry starting with a punctuation character will be a comment
#You need to remove ; from begining of values and replace with your
#own values below if you need change settings.
[SERVICES] #默认DHCP和DNS功能都启动，在此处配置启动那个功能——如下仅启动DNS
#Specify the service you want to use
#Default is both services
DNS
;DHCP
[LISTEN_ON] #多网卡时配置监听那个网卡
#Specify the Interfaces you would like Server to listen
#if you have more than one NIC card on your server
#always specify which cards will listen DHCP/DNS requests
#Requests from diffent Interfaces look for matching DHCP ranges.
#Requests from relay agents look for matching range to relay agent IP.
#upto 125 interfaces can be specified.
#Default is all Static interfaces
;192.168.1.156
[LOGGING] #服务版是启动日志
#Logging will be done only if run as Service.
#LogLevels can be set as None, Normal or All
#Logging Level has be specified separately for DHCP and DNS
#It is advisable to keep logging to Normal, Normal include errors
#and DHCP Lease renewal messages. Normal is defaul logging also.

[DNS_ALLOWED_HOSTS] #允许那些IP使用该服务
#These are permitted hosts for DNS Query.
#Hosts having IP address within these ip ranges
#only will be responded to DNS requests.

#limit is 125 entries. Each such entry can
#have upto 2 child DNS Servers, separated

#You can also use entries here as DNS_PROXY
#and forward queries to any specified DNS server.
#based on matching of last part of query.

[TIMINGS]

#specify 0 for infinity.

;Retry=100
;Expire=360000

#Below are DNS caching timings, You should never specify them
#under Production Environment as this may make cache entries stale.
#DNS Entries should expire as specified by their auth DNS Servers.
#However you can override for testing purposes only
;MinCacheTime=100
;MaxCacheTime=1000
[HTTP_INTERFACE]
#This is http inerface for viewing lease status,
#Default is localhost interface, port 6789
#You can change it here to any network interface and port
;127.0.0.1:6789
#DHCP Sections
#Sections below are other DHCP Sections. Clients can be allotted addresses in
#two ways, dynamically from DHCP Range or statically. For static addresses,
#client section needs to be created for each static client
#against its MAC Address. BOOTP clients are allways static.
#The DHCP Ranges are grouped into [DHCPRange]s, so that range specific options
#can be specified for a group of ranges at one place. The totol ranges together
#in all [DHCPRange]s is also 125 and there can also be 125 [DHCPRange]s max.
#You can specify one or more ranges in each [DHCPRange] section, in format
#specified.DHCP Server will alot addresses from these ranges. Static Hosts
#and BootP clients do not need ranges. do not specify any [DHCPRange]
#or DHCP_Ranges if all clients are Static.
#The Policy for alloting dynamic address is:_
#1)First Look for MacAddress in DHCP Client sections
#2)If not found look for old expired/active address of same host
#3)If not found, look if DNS has matching hostname entry and this IP is free
#4)If not,look at requested IP Address and it is free
#5)If not, allot virgin IP Adress, if any available
#6)If no virgin IP address exists, allot expired IP address of other host.
#From 2) to 6), requests from diffent Interfaces look for matching DHCP ranges
#of Interface IP and requests from relay agents look for matching range to
#relay agent IP.
#All the ranges in a DHCPRange section can be further restricted
#by FilterMacRange, FilterVenderClass and FilterUserClass
#If for example Mac Range is specified, then this section;s ranges
#will only be available to hosts, whoes Mac Address
#Falls in this range. Also if any host has matching FilterMacRange in
#any DHCPRange section then other DHCP Range sections
#without FilterMacRange or not having matching Mac Range will
#not be available to it. Each Manufacturer has a fixed Mac Range.
#Same Mac ranges can repeate in many DHCPRange sections.
#For FilterVendorClass (option 60) and FilterUserClass filter (option 77),
#the range would only be available to matching value of FilterVenderClass
#and FilterUserClass sent in client request. If FilterVenderClass and
#FilterUserClass do match in one or more ranges, other ranges with missing
#or not matching values would not be available to such clients.
#You can specify upto 32 FilterMacRange, FilterVenderClass and
#FilterUserClass in each [DHCPRange].
#You dont need to specify any filters for relay agent. The range is automatically
#selected based on relay agent IP and range;s subnetmask. Relay agent always sends
#it;s subnet side IP. This server would only use the DHCP Range, which contains this IP.
#This would ensure that correct range is used. This feature eliminate the need of
#additional configuration. For matching purpose, range is recalculated using
#Subnet Mask of range and Relay Agent IP.
[RANGE_SET]
#This is first and simple DHCP range section example,
#This example may be good enough for simple/home use.
#If you need range filters, look at example below
DHCPRange=192.168.0.1-192.168.0.254
;DHCPRange=192.168.4.1-192.168.4.254

;43="this is return string"
#or use the byte array in value
;43=123,56,87,123,109,0,23,56,156,209,234,56
#or use the hex array in value
;43=a6:87:b6:c9:ae:eb:89:09:a4:67:d5
[GLOBAL_OPTIONS]
#These are global DHCP Options and would supplement
#client specific options and [RANGE_SET] options.
#Options tags start with 1 and goes up to 254, you can
#always specify option like 1=255.255.255.0, but it may
#be difficult to remember option tags. Try using Option Names
#If no matching name found, you can use tag=value (flat options)
#You can also specify the value as byte array or even hex array.
#Some options having sub-options can only be specified as hex/byte
#array If options have client specific values, move/copy them
#to specific Static Client's section. If any option has DHCP range
#specific value, move/copy them to [RANGE_SET] sections.
#You may quote stings values (must quote if sting contain chars
#like comma, dot or colon) for example NDS_Tree_Name="my.NDS.Tree"
#or 43="this is return string" or use the byte array in value
#like 43=123,56,87,123,109,0,23,56,156,209,234,56 or use the hex
#array in value 43=a6:87:b6:c9:ae:eb:89:09:a4:67:d5
