Facebook debugger is caching different IP addresses for same domain

Question

I have problem with Facebook debugger, I tried to scrape domains few times, and I got strange results.

Facebook debugger is caching different IP addresses for the same domain. I saw a few different IP addresses in half hour of scraping.

• 158.69.39.225
• 185.80.69.2
• 51.15.154.158

Sites is located on 192.99.106.21. (ping)

I suspect that the problem is dedicated to the http and https protocol or with DNS because debugger showing crazy redirect cycles.

• Input URL > https://kurir.rs/
• 301 HTTP Redirect > http://www.kurir.rs/
• 301 HTTP Redirect > https://www.kurir.rs/

For example:

• When I scrape http://kurir.rs/ i got 158.69.39.235
• When I scrape https://kurir.rs/ 51.15.154.158
• There is no scheme for this, I also got 185.80.69.2 few times.

Espreso.rs and kurir.rs is websites with a lot of traffic. I doubt that that affecting our FB organic reach, which is serious problem for us.

I already contacted them but I want to hear another opinion.
