DuckDuckBot list incomplete?

[anvilvapre]

Not all IP's listed on https://duckduckgo.com/duckduckbot.json are in the duckduckbot.ips list i.e. 68.219.152.220.

Also seems you take the ips from the html page, where there is a json.

The list https://github.com/AnTheMaker/GoodBots/blob/main/iplists/duckduckbot.ips was updated last 5 months ago.
