| Variety of addresses | 4.3 billion | 3.4 x 10^38 |
| Format | 4 octets | 8 hexadecimal teams |
| Default subnet masks | 255.255.255.0 | ffff:ffff:ffff:ffff::/64 |
6. Format
The format of IP addresses is a vital facet of understanding “was ist eine IP adresse”. IP addresses are written in a particular format to make sure that they are often simply recognized and routed on the web.
- IPv4 addresses are written as 4 numbers separated by durations. Every quantity represents a byte of the IP tackle. For instance, the IP tackle 192.168.1.1 is written as 4 bytes: 192, 168, 1, and 1.
- IPv6 addresses are written as eight teams of 4 hexadecimal digits separated by colons. Every group of 4 hexadecimal digits represents a 16-bit phrase. For instance, the IPv6 tackle fe80::1 is written as eight teams of 4 hexadecimal digits: fe80, 0000, 0000, 0000, 0000, 0000, 0000, and 1.
The format of IP addresses is necessary as a result of it permits routers and different networking units to shortly and simply determine and route site visitors. The completely different codecs of IPv4 and IPv6 addresses replicate the completely different sizes of the 2 tackle areas. IPv4 addresses are 32 bits lengthy, whereas IPv6 addresses are 128 bits lengthy. Which means that there are a lot of extra attainable IPv6 addresses than IPv4 addresses.
7. Task
The task of IP addresses might be both static or dynamic. Static IP addresses are manually assigned to units and don’t change over time. Dynamic IP addresses are routinely assigned to units by a DHCP server and may change over time. Each static and dynamic IP addresses have their very own benefits and drawbacks.
Static IP addresses are helpful for units that must be simply accessible from different units on the community. For instance, an online server or a file server could also be assigned a static IP tackle in order that customers can at all times discover it. Dynamic IP addresses are helpful for units that don’t must be simply accessible from different units on the community. For instance, a laptop computer or a smartphone could also be assigned a dynamic IP tackle.
The task of IP addresses is a vital a part of community administration. By understanding the various kinds of IP tackle task, community directors can be sure that units on their community have the right IP addresses for his or her wants.
