ddresses. Most carriers have transitioned to IPv6. The IPv6 IEEE standard was published in 1998. Most new routers, web browsers, and computers are compatible with both IPv4 and IPv6. The transition to IPv6 can be complex because it means assigning new addresses to every device with an IP address, including routers, firewalls, network management software, and all servers, including e-mail servers. In addition, it's not a simple matter to determine which applications and devices are compatible with IPv6. Enterprises that transition to IPv6 often need to be able to handle messages that are still in the older IPv4 scheme. Encapsulating IPv6 addresses within IPv4 can address this problem. There are also software packages that support both protocols. SECURITY: CONNECTED, UBIQUITOUS NETWORKS- VULNERABLE TO MALICIOUS HACKERS Hackers exploit the inherent openness of the Internet and common protocols to steal personal and corporate information, earning billions of dollars from selling www.TechnicalPDF.com information they steal. Hacking into networks and selling information is not only lucrative, it's comparatively punishment free. Hackers are rarely caught and jailed for stealing personally identifiable information such as Social Security numbers, birthdays, and intellectual property from businesses. For one thing, it's not always easy to trace IP addresses back to their origin; secondly, many countries from which hackers launch attacks don't have extradition treaties with Europe and the United States. Without a treaty, attacked countries are not able to extradite hackers and bring them to trial. This prevents hackers from countries such as Russia, China, and Iran from being brought to trial in countries such as the United States and many in Europe in which hacking attacks occurred. Extradition treaties are agreements between countries whereby a country in which a crime took place can receive permission to bring criminals back to trial in the country of their suspected crime.
