However, both protocols can exist simultaneously on a network. IPv6вЂ™s representation in hexadecimal, colon-separated notation makes it more suitable for mobile networks. Mobile compatibility вЂ“ IPv4вЂ™s use of the dot-decimal notation makes it less suitable for mobile networks.Security вЂ“ Security is built into the IPv6 protocol, whereas, with IPv4, security is dependent on the application.Checksum вЂ“ IPv4 has checksum fields, while IPv6 offers none.

Size of IP addresses вЂ“ IPv4 addresses are 32-bits by design, while IPv6 addresses are 128-bit.Meanwhile, IPv6 addresses are alphanumeric and separated by columns (:). Address style вЂ“ IPv4 addresses are numeric and have their binary bits separated by dots (.).Here are the key differences between these two protocols вЂ“ Sadly, since these two protocols cannot communicate with each other, IPv4 will not become obsolete anytime soon. IPv6 was designed to be the next-generation protocol that fixes the limitations and flaws in IPv4. Here is an article by HowToGeek exlaining how IP addresses work. Note that while IPv4 offers a limited number of addresses that can be assigned, this is not the case with IPv6. When you attempt to connect to their internet, your online activity first goes to your ISP and is immediately routed to your device via your IP address. For instance, if AT&T or COX is your ISP, theyвЂ™re responsible for assigning IPs to your devices. Since ISPs provide you with access to the internet, itвЂ™s their responsibility to assign an IP address to your device. IP addresses are typically assigned to devices by an Internet Service Provider (ISP). Read more about IP addresses on Wikipedia. Whether youвЂ™re simply surfing the web, watching a video on YouTube, or booking your next holiday, IP addresses are certainly involved. IP addresses are like GPS locations for devices (including servers) on any network. Since they were first developed in the 1970s, IP addresses have evolved to define how devices interact on the internet. You could view this as a mailing address, just for your online activity. Websites that are HTTPS secured only exclude the individual pages you visit from being monitored, your domains can still be scrutinized regardless.An Internet Protocol (IP) address is essentially a unique identification number for machines connected to any network. Your internet provider can see any website you visit, if it is not HTTPS secured. These browsing activity logs are handed over to multiple government agencies who donвЂ™t even need a warrant to acquire such information. Being their customer they are aware of your name, address, cell number, bank account details, credit card number, credit history and maybe even more.Д¬ountless countries, including UK and Australia, have ISPs maintain logs of your browsing history as they per a requirement. Your ISP knows more in-depth personal information about you than your friend. Internet Service Providers (ISPs) are party to even more information. After that, you are either targeted for marketing and shown content and advertisement that may suit your liking or your data is sold to the person bidding highest. These pieces of information are put together along with the websites you visit, the kind of content piques your interest and who you communicate with. By doing this, it is easy to build an entire profile about you. They combine your IP address with more information gathered and extracted from metadata, trackers, cookies, owners of website, advertisers and marketers. The landing websites can reveal even more.
