Question Why is my firewall blocking IT companies' ip adresses?


Oct 31, 2017
I am using mcafee, both on my computers, and I noticed that I have "suspicious incoming connections" blocked such as ANS communications,Akamai technologies,Google LLC, DigitalOcean,InstartLogic,CloudFlare,and some random ip's from the other half of the planet (Texas, Netherlands etc.),also some IPv6 adresses, which I can't even check,and a bunch of private adresses which are trying to access my TCP/UDP ports. It says that these private IPs' source is my own DNS server. I also have some IPs which are pointing towards some kind of internet access points (idk their name), they are providing internet, and they owed by Internet providers (TELEKOM). Should I be worried, or this is normal? Also I tought that Mcafee just trying to flex that it blocked so much "suspicious things" so I'll renew my subscription. I mean, I didn't see this in any other anti-malware programs. I think they also have firewalls, but those are doing it "silently". Most of them are linked to big companies, so I think it's their tracking cookies, so they see the consumers interests, thus they can use it for their marketing. I am more worried about those private IPs within my local network with the source of my own DNS-DHCP provider. I'll write some ports that these tried to access (in case if someone would recognize them):
UDP-63764. 64138, 59672, 58952, 62037,59566, 50463, 55884, 52370, 50476, 59438
UDP- 8999, 1900, 5355(by the random ipv6 adress),
TCP-52404, 52397, 52398, 51922, 51213, 51514, 53409, 50356
Some big UDP- packages to analyze my system (according to Mcafee)
Can I protect myself better against these? I saw a lot person with this problem, and one of them got an advice to replace Mcafee with Comodo. Should I? Or are there other softwares to block these attempts?
Thank you for reading this far, and I would appreciate any kinf of help.
