Remove duplicate text lines with the deduplicator, preserving first-seen order — clean email lists and logs. Dedupe 10,000 rows without Excel gymnastics — local processing, free, no signup.
Masking (zero last octet) keeps geo utility; deterministic unsalted SHA-256 hashing (first 8 hex chars mapped to 4 octets) preserves joinability across datasets. Pick per analysis need: /24 zeroes the last octet, /16 zeroes the last two.
Yes — IPv6 keeps the first 48 bits (first 3 hextets) with the rest zeroed, always. Full-zeroing kills all utility.
Proper masking plus no re-identification keys generally qualifies; hashed IPs with retained salts may still count as personal data. Know your standard.
No — anonymization runs locally in your browser. Source logs never leave your device.
