The difference between automatically obtaining an IP address and broadband dial-up Internet access

The main difference between automatically obtaining an IP address and broadband dial-up Internet access is: address allocation: the former allocates dynamic IP through DHCP, and the latter allocates temporary IP through PPP. Configuration complexity: The former requires almost no configuration, while the latter requires configuring dial-up settings. Connection duration: The former is usually permanent, while the latter requires redialing each time. Flexibility: The former requires a DHCP server, the latter does not. Security: The latter is more secure in some cases because it uses user authentication.

The difference between automatically obtaining an IP address and broadband dial-up Internet connection

Automatically obtaining an IP address

• Obtaining an IP address automatically is a way of allocating an IP address through the DHCP protocol (Dynamic Host Configuration Protocol).
• The DHCP server is responsible for managing the pool of available IP addresses and automatically assigning IP addresses to devices connected to the network.
• When using automatic IP address acquisition, the device does not need to be configured with a specific IP address, subnet mask, or gateway information.
• This method is simple and fast, making it ideal for the average home user and most corporate networks.

Broadband dial-up Internet access

• Broadband dial-up Internet access is a way to connect to the Internet through a dial-up modem.
• Users need to call a specific phone number and authenticate using a username and password provided by their ISP (Internet Service Provider).
• After the dial-up connection is established, the device will obtain a temporary IP address, which is only valid during the connection period.
• This method requires configuring specific dial-up settings, including phone number, username, and password.

Main difference

• Address allocation: Automatically obtain IP address and dynamically allocate IP address through DHCP, while dial-up Internet access through PPP (Point-to-Point Protocol) dial-up connections are assigned temporary IP addresses.
• Configuration complexity: Automatically obtaining an IP address requires almost no configuration, while dial-up Internet access requires configuring dial-up settings.
• Connection duration: Automatically obtaining an IP address is usually permanent, while dial-up Internet connections require redialing each time.
• Flexibility:Dial-up Internet access can be used in environments without a DHCP server, while automatically obtaining an IP address requires a DHCP server.
• Security: Dial-up Internet access may be more secure than automatically obtaining an IP address in some situations because it uses user authentication.
