Bkjia.com exclusive Article] Currently, ICANN has allocated IPv4 addresses. It is reasonable to say that some organizations should be somewhat nervous, because there is no IP address, how can we ensure that some network devices are connected to the Internet? This is because many organizations currently use the NATNetwork Address Translation technology. Next, we will use a real-world running instance and some mechanisms and principles to help you fully

in the form of class A address, which is generally used within the large group. The classification structure of the standard IP address is used in the form, and it is irrelevant to the global Class A address of the public network. ICANN does not assign Class A network address to China, china Mobile and China Unicom only have 26 and 28 Class B addresses respectively. With this address, you can only access China Mobile's internal wap network. The secon

1. What is the network layer?The network layer in the TCP/IP system provides a simple, flexible, non-connected, and best-effort delivery of packet services. The network layer does not provide a commitment to quality of service, does not guarantee the time limit for packet delivery, and the packets transmitted may be error, lost, duplicated, and out of sequence.2. Internet Protocol IP1. Virtual Interconnect NetworkThe IP network is virtual. As seen from the network layer, the IP network seems to
BGP ASN uniquely identifies one organization that considers itself autonomous from other organization. Each company whose enterprise network connects to the Internet can is considered to be a autonomous system and can be igned a BGP ASN. (Iana/icann also assigns globally unique Asns) Additionally, each ISP have an ASN, or possibly several, depending on the size of the ISP.6. BGP uses the As_path to perform, key functions:choose the best route for a p
rules to prevent duplication of domain names. DNS rules about domain names are similar to the express systems in our lives, using hierarchical address structures. Express delivery system to send someone mail items, the address may be: China, Guangdong Province, Guangzhou City, Fanyu District, Zhongshan West Road, No. 12th XXX. And a domain name looks like this groups.google.com (why not com.google.groups?) I guess it might have something to do with the foreigner's habit of writing an address.Fo
