I know this question, but if the IP format is banned, the website using the IP format will not be collected. Although it is not used a lot, it will still be encountered. There is no better way to think about it now.

I understand what you think, but the intranet address segment 10.0.0/8 172.16.0.0/12 192.168.0.0/16 should not appear in URL requests. You should disable them
