Socketbench, a 19-tool network workbench

Field notes

The page arranges 19 utilities as a numbered workbench, covering network lookups, encoding, structured-data formatting, cryptographic hashes, IP conversion, regular expressions, UUIDs, cron expressions, and date calculations. DNS requests are described as going directly to public DNS-over-HTTPS resolvers, while the browser-based ping substitute sends four HTTP probes rather than ICMP packets. The JWT tool explicitly limits itself to decoding header and payload data, not signature verification.
