IP Addresses Have Class!?

In this video, we dive deep into the world of IP address ranges, covering everything from Class A, B, C, D, and E to APIPA, loopback addresses, and private ranges for Class A/B/C networks. Learn how these address ranges are structured, their significance in networking, and practical applications. #IPAddresses #Networking #ClassA #ClassB #ClassC #ClassD #ClassE #APIPA #Loopback #PrivateRanges #VLSM #CIDR Make sure to like, comment, and subscribe for more networking tutorials and discussions! ===== VIDEO Notes: RFC 870: Assigned Numbers https://datatracker.ietf.org/doc/html... October 1983 NOTE: IPs in Class A, B, C, formats sold in /8, /16, and /32 blocks respectively to organizations whether they needed all the IPv4 Addresses or not. NOT TOTALLY RELEVANT IN THE VIDEO RFC 1466: Guidelines for Management of IP Address Space https://datatracker.ietf.org/doc/html... May 1993 RIR - regional internet registries to distribute IPs rather than rely on IANA to handle all IPs. regions had different IP ranges Use class C blocks or contiguous class C blocks where applicable.

Examples 012.rrr.rrr.rrr ATT 017.rrr.rrr.rrr Apple 019.rrr.rrr.rrr Ford 053.0.0.0 Mercedez-Benz 73.0.0.0 Comcast Class B: Public IP Range: 128.0.0.0 to 191.255.0.0 First octet value range from 128 to 191 Private IP Range: 172.16.0.0 to 172.31.255.255 (See Private IP Addresses below for more information) Subnet Mask: 255.255.0.0 (16 bits) Number of Networks: 16,382 Number of Hosts per Network: 65,534 Class C: Public IP Range: 192.0.0.0 to 223.255.255.0 First octet value range from 192 to 223 Private IP Range: 192.168.0.0 to 192.168.255.255 (See Private IP Addresses below for more information) Special IP Range: 127.0.0.1 to 127.255.255.255 (See Special IP Addresses below for more information) Subnet Mask: 255.255.255.0 (24 bits) Number of Networks: 2,097,150 Number of Hosts per Network: 254 Class D: Range: 224.0.0.0 to 239.255.255.255 First octet value range from 224 to 239 Number of Networks: N/A Number of Hosts per Network: Multicasting Class E: Range: 240.0.0.0 to 255.255.255.255 First octet value range from 240 to 255 Number of Networks: N/A Number of Hosts per Network: Research/Reserved/Experimental Private IP Addresses: Class A Private Range: 10.0.0.0 to 10.255.255.255 Class B Private APIPA Range: 169.254.0.0 to 169.254.255.255 Automatic Private IP Addressing (APIPA) is a feature with Microsoft Windows-based computers to automatically assign itself an IP address within this range if a Dynamic Host Configuration Protocol (DHCP) server is not available on the network. A DHCP server is a network device that is responsible for assigning IP addresses to devices on the network. At your home, your Internet modem or router likely provides this functionality. In your work place, a Microsoft Windows Server, a network firewall, or some other specialized network device likely provides this functionality for the computer at your work environment. Class B Private Range: 172.16.0.0 to 172.31.255.255 Class C Private Range: 192.168.0.0 to 192.168.255.255 Special Range: IP Range: 127.0.0.1 to 127.255.255.255 are network testing addresses (also referred to as loop-back addresses). These are virtual IP address, in that they cannot be assigned to a device. Specifically, the IP 127.0.0.1 is often used to troubleshoot network connectivity issues using the ping command. Specifically, it tests a computer's TCP/IP network software driver to ensure it is working properly. ================================================== 🐦 Follow Kelley Parker on Social Media: ➡️ https://www.x.com/kelleyparker ➡️   / kelleyparker_   ➡️ https://www.tiktok.com/kelleyparker ➡️   / kelleyparker   ➡️ https://www.github.com/kelleyparker ➡️   / kelleyparker11   Learn OBS Studio! ➡️ https://www.udemy.com/course/obsin123/
