Webli Residential Internet connections, whether broadband or dialup usually use dynamic IP addresses, while commercial leased lines and servers have static IPs, so they can always be reached at the same address.The need for dynamic IP addresses arises from the limited number of IP addresses available in IPv4 (Internet Protocol version 4). Theoretically, there can be about four billion IPs in the Internet, however, the actual number is much lower for various reasons. Something had to be done to ensure supply of address space, at least until IPv6 is widely implemented on the Internet, allowing for 128bit IP addresses. The limited IP address space is one of the reasons for the wide use of NAT routers, as well as DHCP and leasing of dynamic IP addresses.
Webli DHCP Network
The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on Internet Protocol (IP) networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services. With DHCP, computers request IP addresses and networking parameters automatically from a DHCP server, reducing the need for a network administrator or a user to configure these settings Obtain an IP address automatically.
Computers use the Dynamic Host Configuration Protocol for requesting Internet Protocol parameters from a network server, such as an IP address. The protocol operates based on the client-server model. DHCP is very common in all modern networks ranging in size from home networks to large campus networks and regional Internet service provider networks. Most residential network routers receive a globally unique IP address within the provider network. Within a local network, DHCP assigns a local IP address to devices connected to the local network.
Webli Static Network
Static IP addresses are reserved for you statically and don't change over time. Even with always-on broadband connections, it's easy to just lease IP addresses as needed. That's why the Static IP addressing is widely used today, especially for residential connections where users run servers. The downside is, your IP address, or "phone number" if you will, can change any time you get disconnected, there is a power outage, ISP maintenance, etc. The fact that you get disconnected does not necessarily mean the IP address is going to don't change, just as the fact that you get the same IP address mean it is assigned statically. Use the IP address manually.
