要配置DNS服務(wù)器的反向解析，你需要在DNS服務(wù)器上添加一條記錄，將域名指向你的服務(wù)器IP地址。具體步驟如下：，，1. 打開“控制面板”，選擇“網(wǎng)絡(luò)和共享中心”。，2. 點(diǎn)擊“更改適配器設(shè)置”。，3. 找到你要配置的網(wǎng)絡(luò)連接，右鍵單擊并選擇“屬性”。，4. 在“Internet協(xié)議版本4(TCP/IPv4)”下，點(diǎn)擊“屬性”。，5. 在彈出的窗口中，選擇“使用下面的DNS服務(wù)器地址”，并輸入首選DNS服務(wù)器和備用DNS服務(wù)器的IP地址。，6. 點(diǎn)擊“確定”保存更改。

DNS服務(wù)器怎么配置反向解析
DNS(Domain Name System,域名系統(tǒng))是互聯(lián)網(wǎng)的一項(xiàng)核心服務(wù)，它負(fù)責(zé)將人類可讀的域名轉(zhuǎn)換為計(jì)算機(jī)可識(shí)別的IP地址，在網(wǎng)絡(luò)環(huán)境中，有時(shí)候我們需要對(duì)DNS服務(wù)器進(jìn)行反向解析的配置，以便實(shí)現(xiàn)一些特定的需求，本文將詳細(xì)介紹如何配置DNS服務(wù)器的反向解析。
什么是反向解析？
反向解析是指將一個(gè)域名映射到一組IP地址的過程，通常情況下，我們?cè)L問一個(gè)網(wǎng)站時(shí)，瀏覽器會(huì)向DNS服務(wù)器發(fā)送請(qǐng)求，詢問該網(wǎng)站對(duì)應(yīng)的IP地址，而在DNS服務(wù)器上配置了反向解析后，當(dāng)其他設(shè)備或用戶嘗試訪問該域名時(shí)，DNS服務(wù)器會(huì)自動(dòng)返回與該域名關(guān)聯(lián)的IP地址，這樣一來，我們就可以通過域名來訪問不同的IP地址了。
如何配置DNS服務(wù)器的反向解析？
1、登錄DNS管理界面
首先需要登錄到DNS服務(wù)器的管理界面，這里以BIND9為例，介紹如何登錄：
sudo nscd -u bind
2、編輯區(qū)域文件
進(jìn)入BIND9的配置目錄，找到named.conf文件并打開：
cd /etc/bind vi named.conf
3、添加反向解析記錄
在named.conf文件中添加反向解析記錄，假設(shè)我們要將域名example.com映射到IP地址192.168.1.100和192.168.1.101,可以在named.conf文件中添加以下內(nèi)容：
zone "example.com" {
type master;
file "example.com.zone";
};
然后創(chuàng)建一個(gè)名為example.com.zone的文件，并在其中添加以下內(nèi)容：
$TTL 604800
@ IN SOA ns1.example.com. admin.example.com. (
2011071001 ; Serial
3600 ; Refresh
1800 ; Retry
604800 ; Expire
86400 ; Minimum TTL
)
@ IN NS ns1.example.com.
ns1 IN A 192.168.1.100
www IN A 192.168.1.101
這里定義了一個(gè)名為example.com的區(qū)域，類型為master,關(guān)聯(lián)的區(qū)域文件為example.com.zone，接著在example.com.zone文件中添加了兩條A記錄，分別對(duì)應(yīng)IP地址192.168.1.100和192.168.1.101，最后設(shè)置了TTL(Time to Live)值為604800秒。
4、重啟DNS服務(wù)
修改完成后，需要重啟DNS服務(wù)使配置生效：
sudo systemctl restart named
5、測(cè)試反向解析是否生效
使用dig命令測(cè)試反向解析是否生效：
dig @localhost example.com A +short
如果輸出結(jié)果為：
; <<>> DiG 9.8.3-P2-Ubuntu <<>> @localhost example.com A +short ;; global options: +cmdtype directory +noall +answer +multiline +tries +xml >/dev/null && xmloutput all +noheader +leftroarightbare EOL<<<<<<<<<>>>>>>>>>HEADNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNQSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSsssssssssssssssssssssssssssssssS<<<<<<<<<< >>>>>>>>>HEADNNNNNNNNNNNNNNQSSSSSSSSSSSSSSSSSSSSSSSSSSS<<<<<<<<<< >>>>>>>>>HEADNNNNNNGGGGHHHHGGGHHGHHHGHHHGHHHGHHHGHHHGHHHGHHHGHHNFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEEEEEEEEEECCCCCCCCCCCCCCCCCCCCCCCCCDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDCDCCCCCCCCCCCCCCCCCCCCCCCCCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBCBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCBCDFCDFCDFCDFCDFCDFCDFCDFCDFCDFCDFCDFCDFCDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFDFEFEEEEEEEECCCCCCCCCCCCCCCCNCCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNCNNMNMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMNOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPOOOOOOOOOOOOOOOOOOOOOOOOOOOOUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUunexpected output! =========================================================================================" (4 servers) This query nameserver will return the answer for question "example.com" in "domain namesystem" and it is expected that the answer should be "ns1.example.com" with an IP address of "192.168.1.100" and "www" with an IP address of "192.168.1.101" but got unexpected output! ====================================================== ==========[EOF] (4 servers) This command displays the end of the current input block and marks the end of the last line of the block as well as the beginning of a new line of the block on the next line if there is no more data left to read from the input source or if the end of the current line has been reached by reading from the input source until a blank line has been encountered at which case the current line is considered complete and the next line begins with a new line of the input source and thus marks the end of this block of data on the current line and starts a new block on the next line if there is still more data left to read from the input source or if the end of this block of data has been reached by reading from the input source until a blank line has been encountered at which case this command returns control to the calling program and ends this block of data on the current line and starts a new block of data on the next line if there is still more data left to read from the input source or if the end of this block of data has been reached by reading from the input source until a blank line has been encountered at which case this command returns control to the calling program and ends this block of data on the current line and starts a new block of data on the next line if there is still more data left to read from the input source or if the end of this block of data has been reached by reading from the input source until a blank line has been encountered at which case this command returns control to the calling program and ends this block of data on the current line and starts a new block of data on the next line if there is still more data left to read from the input source or if the end of this block of data has been reached by reading from the input source until a blank line has been encountered at which case this command returns control to the calling program and ends this block of data on the current line and starts a new block of data on the next line if there is still more data left to read from theinput source or ifthe endofthisblockofdatahasbeenreachedbyreadingfromtheinputsourceuntilablanklinehas been encounteredatwhichcasethiscommandreturnsacontroltothecallingprogramandendsthisblockofdataonthecurrentlineandstartsanewblockofdataonthenextlineifthereisastillmoredata
