端口號(hào)作用（共7篇）篇：端口號(hào)的作用及常見(jiàn)端口號(hào)用途

端口號(hào)的作用及常見(jiàn)端口號(hào)用途

在網(wǎng)絡(luò)技術(shù)中，端口（Port）大致有兩種意思：一是物理意義上的端口，比如，ADSLModem、集線器、交換機(jī)、路由器用于連接其他網(wǎng)絡(luò)設(shè)備的接口，如RJ-45端口、SC端口等等。二是邏輯意義上的端口，一般是指TCP/IP協(xié)議中的端口，端口號(hào)的范圍從0到65535，比如用于瀏覽網(wǎng)頁(yè)服務(wù)的80端口，用于FTP服務(wù)的21端口等等。我們這里將要介紹的就是邏輯意義上的端口。那么TCP/IP協(xié)議中的端口指的是什么呢？如果把IP地址比作一間房子，端口就是出入這間房子的門。真正的房子只有幾個(gè)門，但是一個(gè)IP地址的端口可以有65536個(gè)之多！端口是通過(guò)端口號(hào)來(lái)標(biāo)記的，端口號(hào)只有整數(shù)，范圍是從0到65535.端口有什么用呢？我們知道，一臺(tái)擁有IP地址的主機(jī)可以提供許多服務(wù)，比如Web服務(wù)、FTP服務(wù)、SMTP服務(wù)等，這些服務(wù)完全可以通過(guò)1個(gè)IP地址來(lái)實(shí)現(xiàn)。那么，主機(jī)是怎樣區(qū)分不同的網(wǎng)絡(luò)服務(wù)呢？顯然不能只靠IP地址，因?yàn)镮P地址與網(wǎng)絡(luò)服務(wù)的關(guān)系是一對(duì)多的關(guān)系。實(shí)際上是通過(guò)“IP地址+端口號(hào)”來(lái)區(qū)分不同的服務(wù)的。服務(wù)器一般都是通過(guò)知名端口號(hào)來(lái)識(shí)別的。例如，對(duì)于每個(gè)TCP/IP實(shí)現(xiàn)來(lái)說(shuō)，F(xiàn)TP服務(wù)器的TCP端口號(hào)都是21，每個(gè)Telnet服務(wù)器的TCP端口號(hào)都是23，每個(gè)TFTP(簡(jiǎn)單文件傳送協(xié)議)服務(wù)器的UDP端口號(hào)都是69.任何TCP/IP實(shí)現(xiàn)所提供的服務(wù)都用知名的1～1023之間的端口號(hào)。這些知名端口號(hào)由Internet號(hào)分配機(jī)構(gòu)（InternetAignedNumbersAuthority,IANA）來(lái)管理。IP協(xié)議是由TCP、UDP、ARP、ICMP等一系列子協(xié)議組成的。其中，主要用來(lái)做傳輸數(shù)據(jù)使用的是TCP和UDP協(xié)議。在TCP和UDP協(xié)議中，都有端口號(hào)的概念存在。端口號(hào)的作用，主要是區(qū)分服務(wù)類別和在同一時(shí)間進(jìn)行多個(gè)會(huì)話。7781=accu-lmgraccu-lmgr7789=ICQKiller7932=DataResourceManager7933=BusineRulesManager7999=irdmi2iRDMI28000=irdmiiRDMI8032=pro-edProEd8400=cvdcvd8401=sabarsdsabarsd8402=abarsdabarsd8403=admindadmind8450=npmpnpmp8473=vp2pVitualPointtoPoint8888=NewsEDGEserver8889=DesktopDataTCP18890=DesktopDataTCP28891=NESSapplication
