Bulk MAC Address Lookup
Preview, look up, and export your list. Your input stays in your browser.
Choose Network output for ARP, ip neigh, or MAC-table text. Review what was extracted before lookup.
Up to 2,000 entries, including duplicates and invalid fields, and 5 MiB. Oversized input is rejected, never truncated. Network output also allows at most 2,000 nonblank source lines and 2,000 candidates, including ambiguous values.
Separate entries with newlines, commas, semicolons or spaces. Drop one TXT, CSV or log file here to preview it.
Duplicates are kept by default. Skipped copies remain in the preview and CSV.
Paste a list or load a file to preview it.
Source review
Only one complete colon, hyphen, or dotted address per line is included. Bare hex values and multiple candidates are ambiguous and excluded. Edit the source or choose addresses yourself in List / CSV mode. Other switch formats may need manual preparation.
Review source lines
Source export includes every nonblank line across all filters and pages, including excluded candidates and reasons.
Preview and results
Filtered export includes every matching page. Selected export includes your selection across all filters. CSV keeps invalid, skipped, and unprocessed statuses.
Your preview will show original inputs, normalized addresses, and source line numbers before any lookup runs.
