The current Internet protocol where exhaustion of resources address is worried (IP) IPv4 in the base, administers improvement such as increase, security functional addition of the address space which can be managed and transmission of the data which responds to precedence the next generation Internet protocol which.

IPv6 pass through

Field:
Network technology > network control > IPv6 pass through

At functional one which the rooter and the like has, make the packet of IPv6 communication inside LAN PASS on Internet side.

If IP which is utilized generally with Internet (Internet Protocol) it was IPv4 and the usual rooter did not do, because the utilization of IPv4 it is designed to prerequisite, to do communication outside and with IPv6, e.g., it encapsulates with the IPv4 packet, the rooter could not be passed.

The rooter which had IPv6 pass through function corresponds to the communication with IPv6, also the packet of IPv6 can come and go the inside and outside in the same way as IPv4. Recently the example where the communication service which used IPv6 making use of the internal network of the common carrier is offered has increased, it is the function which becomes necessary in order to utilize this.

IP-VPN

LAN > VPN > IP-VPN

The wide area IP communication network which the common carrier possesses by way of the hypothetical private communication network which is constructed (VPN) is.

When network of remote place is connected with LAN, by way of IP-VPN, it is possible to use in the same way.

Originally, if it is the network where the backbone is used in the IP base, it is called IP-VPN, regardless of the presence of connection with Internet, but usually, through the closed limits IP net which the common carrier constructed to the individual those which were constructed are called IP-VPN. VPN which by the way, is actualized on Internet is called Internet VPN.

As for IP-VPN which does not mind Internet, it is possible to improve security and communication quality.

IPX/SPX

Field:
OS > NetWare > IPX/SPX

The protocol which NetWare of the Novell corporation uses. Because share is high as the protocol which is used for personal computer LAN the related equipment and being abundant, there is an advantage such that program size of the communication driver are small, but the position is decreasing recently with the spread of Internet which uses TCP/IP and the small-scale conversion of the UNIX related system and the gaining force etc of Windows NT.

IP address

Reading: The eye tweet address
Full spelling: Internet Protocol Address
Field:
Network technology > TCP/IP > IP address

The identification number which is allocated to the computer and communication equipment 1 unit 1 it is connected to the IP network of Internet and Intranet etc. On Internet there is no repetition in this numerical value, because, NIC of each country (network information center) does the management of allotment and the like of IP address.

Network of Internet and the like IP (Internet Protocol) with the protocol which is said (protocol) is used for the communication between the equipment. As for IP address those like address of the individual communication equipment and the computer in the network which is used with this IP. Presently to be wide it has spread, “IPv4” (Internet Protocol version 4) with, 8 bits at a time numerical value of 32 bits which were divided in four is used in IP address, as such as “211.9.36.148”, four arranging the number of decimal up to 255 from 0, expresses.
