域名系统 (DNS):
在 DNS 中,借助 DNS 服务器,将域名转换为 IP 地址,将 IP 地址转换为域名。 DNS的架构如下:
动态主机配置协议 (DHCP):
与DNS服务器一样,它并不将域名映射为IP地址或IP地址映射为域名,DHCP服务器用于对主机进行机械配置。
让我们看看 DNS 和 DHCP 之间的区别:
S.NO | DNS | DHCP |
---|---|---|
1. | DNS stands for Domain Name System. | While DHCP stands for Dynamic Host Configuration Protocol. |
2. | It works in 53 port number. | While it works in 67 and 68 port number. |
3. | The protocol supported by DNS are: UDP and TCP. | While in this only UDP protocol is used. |
4. | DNS is decentralized system. | While DHCP is centralized system. |
5. | In DNS, with the help of DNS server, domain names are translated into IP addresses and IP addresses are translated into domain names. | While in DHCP, DHCP server is used to configures the hosts mechanically. |
6. | With the help of DNS, we don’t need to remember the IP address. | It is reliable IP configuration. |
