Notes
- This tool does not store tenant URLs or lookup history.
- The IP range data is served locally from
data/ip_ranges.jsonto avoid CORS issues with the public S3 JSON URL. - The last update time is taken from the S3
Last-Modifiedresponse header and stored locally indata/last_modified.txt. - The local JSON file should be refreshed daily from Okta's published IP range JSON.
