IPv4 interval to CIDR
Break down the starting and ending IPv4 address intervals into the minimum CIDR network segments that are precisely covered.DNS record query
Query A, AAA, CNAME, MX, NS, TXT, CAA, SOA and PTR records.Does ip belong to the network segment
Compare a set of IPv4 addresses with the specified CIDR network segment, and display whether they match one by one.MAC address format conversion
Batch the MAC address format to identify unicast, multicast and local management bits.Common subdomain detection
Quickly check common subdomain prefixes and their public DNS resolution results.IP/CIDR Calculator
Calculate IPv4 and IPv6 segments, address range, mask and number of addresses.IP address format translation
Convert IPv4 and IPv6 canonical formats, integers, hex and binary representations.UserAgent parsing
Identify browsers, operating systems, rendering engines, and device types.Public DNS Daquan
View the IPv4, IPv6 and encrypted DNS addresses of commonly used public recursive DNS.Domain name registration information
Query the domain name registration status, registrar, date, dnssec and name server on this site.IPv4 network segment merge and deduplication
Merge multiple overlapping or adjacent IPv4 segments into the minimum CIDR collection with precise coverage.IPv4 subnet division
Divide an IPv4 segment into equal-large subnets according to a longer prefix, list the scope.IPv4 list sorting and verification
Check the IPv4 list offline, sort by value, deduplicate and mark the wrong line.IPv4 network segment exclusion calculation
Subtract multiple network segments from the underlying IPv4 network segment to output the simplest CIDR collection for the remaining range.IPv6 network segment scope calculation
Calculate the specification address, CIDR network, first and last address and exact address of IPv6.MAC and Modify EUI-64 Demo
Convert the unicast MAC to modify the EUI-64 interface identification and combine it with the self-fill IPv6/64 prefix.DNS reverse PTR record batch generation
In the browser, the complete PTR record text is generated in batches according to self-fill IPv4 or IPv6 and the hostname.
