The IP addresses available to the Internet are called?
Public IP addresses
Which statement accurately describes public IP addresses?
Public IP addresses must be unique across the entire Internet.
My phone company says we are Dynamic and can not set up a static IP is this true?
It is a decision made by the ISP whether or not to allow static IP addresses. Most ISPs, in your case the phone company, do have static IP addresses available for an extra charge. Static IP addresses often require a business internet account.
What is the difference between private IP addresses and public IP addresses?
public ip-addresses are used in the Internet (they are registered addresses). private ip-addresses are used in local networks. imagine you have a computer in your local network that has a public ip-address and your PC has simultaneously an Internet connection: if you try to ping this pc you wouldn't be able to tell which computer is replying, the local one or the webserver.
Who supplies the IP address?
IP addresses are supplied by Internet Service Providers (ISPs), which are organizations that provide users with internet access. When a user connects to the internet, the ISP assigns an IP address from its pool of available addresses. Additionally, in larger organizations or networks, static IP addresses may be assigned by network administrators for specific devices.
Why do you lose ip address?
You might lose your IP address due to various reasons, such as network changes, router resets, or if your Internet Service Provider (ISP) reallocates IP addresses. Dynamic IP addresses, which many ISPs use, can change periodically as they are assigned from a pool of available addresses. Additionally, disconnecting from the network or turning off your device can also result in losing the current IP address.
Under what circumstance would it be appropriate to use private IP address?
The usual reason to use private IP addresses is when you have to share a single public IP address (or a few public IP addresses) among a larger number of computers. Nowadays, this situation is quite common - it is no longer possible to assign a public IP (version 4) address to each and every computer; IP addresses are starting to get scarce. In the scenario mentioned above, private IP addresses according to RFC 1918 are used in combination with NAT (network address translation).
How are IP addresses available to the Internet classified?
public
Is all class B addresses are APIPA addresses?
No, not all Class B addresses are APIPA addresses. APIPA (Automatic Private IP Addressing) specifically refers to the range of IP addresses from 169.254.0.1 to 169.254.255.254, which is used for automatic private addressing when a device cannot obtain an IP address from a DHCP server. Class B addresses encompass a broader range from 128.0.0.0 to 191.255.255.255, which includes both public and private addresses, but only a small subset of APIPA addresses.
What is public ip and private ip address?
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets (local networks): 10.0.0.0 - 10.255.255.255172.16.0.0 - 172.31.255.255192.168.0.0 - 192.168.255.255Also, IP addresses in the range of 169.254.0.0 -169.254.255.255 are reserved for Automatic Private IP Addressing. These IP's should not be used on the Internet. I usually use 192.168.0.1, 192.168.0.2, etc. and a subnet mask of 255.255.255.0 when assigning static IP addresses to computers on a small Local Area Networks (LANs). If a DHCP server is also on the LAN it's scope (range of IP addresses that it can assign to computers on the LAN set to obtain their IP addresses automatically) should be adjusted so it does not interfere with locally assigned static IP addresses.
What process hides multiple IP addresses behind a single IP address?
The process that hides multiple IP addresses behind a single IP address is called Network Address Translation (NAT). NAT allows multiple devices on a local network to share a single public IP address when accessing the internet. It works by translating the private IP addresses of the devices into the public IP address, managing the connections and ensuring that the correct data is sent back to the appropriate device. This enhances security and conserves the number of public IP addresses needed.
What do IP numbers represent?
An IP number is the unique address by which you can reach an individual computer. At least, that was the original idea of IP addresses; if you want to know how this has changed in recent days, do some research on the following topics: IP address exhaustion; private IP addresses; public IP addresses; NAT.
