Assignment Help:

Extranets can also be utilized to link an intranet to the Internet in order that remote offsite access can be built into a company's intranet through an authorized individual. It can facilitate through an extranet.

On the whole, it employs passwords & smart cards to log in to a gateway server which verify the requester's security credentials. If user checks out, he or she is allowed access in the company's intranet structure.

A number of URL address are set aside for intranet & extranet use. In essence since intranets are self-contained networks, the same set of addresses can be utilized through all intranets without conflict. Extranet addresses are designed to identify the intranets they link and correctly preface every intranet address along with an identifier. It allows two interconnected intranets to achieved the same set of address values and keep them from being wrong. One class A address, ranging from 10.0.0.0 to 10.255.255.255 is holed for intranet usage. Again, as an intranet is a self- contained system, it needs only one class A network to designate the major network. Subnetworks employ reserved class B & class C addresses. There are sixteen class B addresses, from 172.16.0.0 ti 172.31.255.255 & 256 class C addresses that range from 192.168.0.0 trhough 192.168.255.255.
