Opera mini and ip?

Good afternoon.
Decided to put protection from bots on the site.. figured out the pros and cons made an interesting conclusion: every ip with an open port 80им - bot. Went did. Watch SP: 141.0.15.49
VAT) 141.0.15.49 th? really Opera mini? whois:
Host: z08-02-01.opera-mini.net
City: Not determined
Country: Norway
IP range: 141.0.14.0 - 141.0.15.255
The name of the ISP: Opera Mini Servers
question: what did I do wrong? To me very important visitors from mobile phones.

Skype, for example, can also keep open port 80.
Skype-%D0%B4%D0%BB%D1%8F-%D0%B4%D0%B5%D0
he is clearly not responding HTTP 1.1 - Josiane75 commented on July 9th 19 at 11:03
Thank you, by the way, that showed this box and constantly had conflicts with Apache - sofia.Runte28 commented on July 9th 19 at 11:06
: It happens :) first come, first serve (i.e. the port). - Daphne_Roob commented on July 9th 19 at 11:09
: I knew a long time ago, but I didn't know that it just turns off. Annoying to turn on Apache, I had to turn off Skype and then enable - sofia.Runte28 commented on July 9th 19 at 11:12

So Opera mini using proxies gives...
so it's 75% not a bot - Josiane75 commented on July 9th 19 at 11:05
Is that a question?) Until I understand the problem, if Opera is subject to the condition, it is necessary to consider,or rather subtract, if I understand correctly, - sofia.Runte28 commented on July 9th 19 at 11:08
: that's just how - Daphne_Roob commented on July 9th 19 at 11:11
In support of the Opera write and ask the range of their IP and describe your problem. For example,if the bot you need to detectit immediately.And so can a robot(script) for each IP address to determine the host. - sofia.Runte28 commented on July 9th 19 at 11:14
