All IPv4 IP addresses can be divided into two major groups: global, or public, or external - this group can also be called 'WAN addresses' — those that are used in the internet, and private, or local, or internal addresses — those that are used in the local network (LAN).
Internet is a public lan?
A LAN is a "Local Area Network". Your cable box is providing one or more Ethernet ports by means of which you can access the Internet.
One of the routers you have to connect to internet, another one you have to connect to the first one using a lan cable. You can use any of lan ports of the first router to connect the second one (except internet port, usually it's marked as WAN or similar to). The lan cable should be connected to the WAN port on the second one. Only in such case it works properly.

When used as a Private Line or MPLS, this is as secure as your lan. If you connect the T1 to the internet, it is not secure. www.intelletrace.com
ip address
Your question is quiet confusing but if you are asking for the protocol for a computer inside the LAN to be able to communicate through the internet then it is the TCP/IP.
The simple answer is that a LAN user (client) will not see all of the packets on the Internet; they will only see the packets for their own LAN segment.
No LAN, only via internet with an EA account.
LAN can be connected by routers . A router can be used to connect to LAN's .a LAN to a WAN and LAN to Internet.
LAN users get access to internet or can communicate with others LAN connected to WAN.
It may be blocked by a firewall, or there actually may be some type of problem. You need to check on the router, and the gateway that is being used for Internet access. Check your own settings as well. If the default gateway address is missing then you will not get Internet access no matter what you do.
Your LAN will need a router and a definition of the default gateway pointing to that router. The router will need an internet connection as well.
It depends on what exactly you are doing outside the Lan. It will definitely fall under TCP/IP, but more specifically, you may be using HTTP, HTTPS, FTP, SMTP.
Yes, but the data traffic will traverse the Internet to reach that public IP address. If the server has another network interface in the same subnet as the connecting device, you can constrain the traffic to the LAN. If the connecting device is instructed to use the public IP address to reach the server, the traffic will first travel to the LAN gateway, which determines the best route for the traffic to reach public addresses. Typically, this would be via an ISP that the gateway is somehow connected to. Please specify your goal in your question to get an optimal strategy as an answer.
DNS doctoring enables an internal host on a LAN to receive the Private ip of an internal server as an answer from a DNS query when using a DNS server that is outside the LAN, such as on the internet. A static NAT translation must also exist to translate the public IP to the private IP. Without DNS doctoring, the external DNS server will reply with the public IP address of the host on the internal LAN.
WAN. LAN is a short range connection, WAN is wide range.
There is no need to "activate" anything. If the LAN card is supported, it will be set up automatically and internet access will be immediately available.
