IPv4 Classes
- Class A: 1.0.0.0 – 126.255.255.255 (large networks)
- Class B: 128.0.0.0 – 191.255.255.255
- Class C: 192.0.0.0 – 223.255.255.255
- Private: 10.x, 172.16-31.x, 192.168.x
- Loopback: 127.0.0.1
IP Address Info: retrieve detailed network metadata for any IPv4 or IPv6 address instantly. Our tool functions as a precise network details tool, breaking down addresses into binary octets and hexadecimal notation for technical analysis. It is an essential ip metadata lookup service for developers who need to verify ipv4 network data or check for loopback 127.0.0.0/8 flags entirely in your browser.
Our IP Address Info tool uses advanced parsing logic to classify addresses against historical classful networking rules and current RFC standards. By providing a clear breakdown of ipv6 address info and cidr range lookup metrics, it simplifies the process of identifying rfc 1918 private ranges and multicast blocks. This free online tool delivers deep technical insights into network addressing, offering a robust isp database lookup experience with no server-side logging.
Class D is the IPv4 multicast range, 224.0.0.0 to 239.255.255.255. It is not assignable to a host - packets to a Class D address are delivered to every member of a multicast group. Class E (240.0.0.0+) is reserved and not routable on the public internet.
The three RFC 1918 blocks: 10.0.0.0/8, 172.16.0.0/12 (so 172.16 through 172.31) and 192.168.0.0/16. Carrier-grade NAT (100.64.0.0/10) and link-local (169.254.0.0/16) are not flagged as private by this tool.
An IPv4 address is just a 32-bit unsigned integer written as four bytes. 192.168.1.1 packs to (192<<24)|(168<<16)|(1<<8)|1 = 3,232,235,777. Some databases and log formats store IPs in this single-integer form for compact indexing.
No - this page is IPv4-only. IPv6 has 128 bits, no classful structure, and a different private-address concept (fc00::/7 ULA, fe80::/10 link-local). A separate IPv6 tool is needed for that.
Analyze your network configuration by using this IP Address Info for all your packet inspection and metadata lookup needs.
