Look for energy bars that have about 5 grams of protein, with some carbohydrate and very little fat. Remember that energy means calories, so watch out for high-calorie bars. They are helpful for athletes on the go, so if you can't eat before a long tennis match, an energy bar can help. Choose protein powders made from whey protein or milk proteins. Use them within 30 minutes after exercising to provide needed amino acids to muscles.
IPv4 was the first standard for IP addresses. 192.168.0.1 is a common example of an IPv4 address. The most recognisable IP addresses are in the range 192.168.0.1 to 192.168.0.255 because these tend to be the ones we use at home. An IP address is a sequence of four blocks of numbers. Each of these blocks is a value between 0 and 255, which means that each block has 256 possible values. So with four blocks allowing for up 256 possible values, IPv4 allowed for around four billion unique addresses, which seemed like a huge amount.
IP Address (Internet Protocol Address). This number is an exclusive number all information technology devices (printers, routers, modems, et al) use which identifies and allows them the ability to communicate with each other on a computer network.
