Practical utilities for firewall configuration, IP planning, and threat-indicator processing.
Create address objects and a static address group from IP addresses and CIDR ranges. Customize names, tags and descriptions.
Calculate subnets, convert IP ranges to CIDRs, and aggregate address lists without expanding coverage.
Create IPv4 address objects and static groups from bulk IPs and CIDRs. Choose append or replace membership and optional VDOM context.
Build display filters for IPv4 and IPv6 addresses, ports, protocols, and two-way conversations.
Extract IPs, domains, URLs, emails, and hashes from text. Normalize, defang, remove duplicates, and export candidate indicators.
Compare exact address coverage across two lists. Review added, removed, and shared IPs and CIDRs.
Find path MTU with Windows and Linux ping commands. Interpret fragmentation errors and calculate your observed packet size.
The tools process entered addresses and generate results locally in your browser. They do not send inputs or results to a server.
