Self-made local DNS servers accelerate bandwidth
When we install a broadband network, the ISP (Internet Service Provider) usually provides several DNS server addresses and then sets them in the Internet TCP/IP protocol settings window. At present, I believe everyone has encountered network problems caused by DNS. For example, the speed of webpage opening is too
Please let me know if there is something wrong or unclear in this article. thank you! DDNS configuration instances (DHCP + DNSDDNS) are a basic task in network management.
