X'inhu Subnetting?
Is-subnetting huwa l-proċess ta' qsim ta' netwerk f'żewġ netwerks iżgħar jew aktar. Dan itejjeb il-fluss tat-traffiku, is-sigurtà, u jissimplifika l-immaniġġjar tan-netwerk.
Notazzjoni CIDR Komuni
- /32: Indirizz IP wieħed Single IP address
- /30: Konnessjoni minn punt għal punt (2 hosts użabbli) Point-to-point link (2 usable hosts)
- /24: Netwerk żgħir standard (254 host użabbli) Standard small network (254 usable
hosts)
- /16: Netwerk korporattiv kbir (65,534 host użabbli) Large corporate network (65,534 usable
hosts)
- /8: Netwerk kbir ħafna (16.7M host użabbli) Very large network (16.7M usable hosts)
Computes network addresses, broadcast addresses, usable host ranges, and CIDR notation for IP subnets. Essential for network planning.
Key Facts
- /24 subnet has 254 usable IPs
- Private ranges: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16
- Subnetting introduced in 1985 (RFC 950)
- CIDR replaced classful networking in 1993
Frequently Asked Questions
What is a subnet?
A logical division of an IP network into smaller segments for security, performance, and efficient IP usage.
What does /24 mean?
First 24 bits are network portion, 8 bits for hosts = 254 usable addresses.
How to calculate hosts?
Formula: 2^(32-prefix) - 2. For /24: 2^8 - 2 = 254 usable hosts.
Public vs private IP ranges?
Private (10.x, 172.16-31.x, 192.168.x) for internal use. Public IPs are globally unique for internet.
