Can someone help me decipher what these log entries mean? Am I getting hacked?
So this is my residential router is a netgear gateway C3700-100NAS with Spectrum Internet. Usually I have no problems. But every so often, intermittently and not very predictable, I would notice my Internet slow down to a crawl, and even pinging 8.8.8.8 or www.yahoo.com will time out or have insane times.
I checked my netgear gateway C3700-100NAS logs and saw this.... Apparently in the span of less than a minute or so there were hundreds of entries for Source of "140.3.230.0" and Target/Destination of "149.104.249.105". Neither of these IPs have anything to do with my residential IP address nor would/should any device on my network be sending nor receiving anything to or from any of these IP addresses.
Based on a simple lookup it appears that 149.104.249.105 is Location is Washington D.C. (Northwest Washington), District of Columbia US - ISP is Cogent Communications and that 140.3.230.0 is Location is Columbus, Ohio US - ISP is DoD Network Information Center.
Can anyone have any idea what is going on?

=== update =====
But one of the problem is I'm with TWC /Spectrum and they statically assign public IP addresses so I'm stuck with the one I have gotten. The only time that I ever gotten a new IP was when my previous router died and when I got a replacement router I had to call them in with the MAC/ CM MAC info and that is after they registered the new Router on their end (also the same C3700 netgear model) I noticed when going to whatismyipaddress that I gotten a new public IP address. It doesn't happen all the time but when it does happen it slows me down to a crawl and usually a reboot stops it, but not because it changed to a different IP address (its static)
The other thing I thought was strange is that assuming the IP address are legit and not spoofed or anything, apparently based on whatever public records available it appears to be coming from a government network going to another government network
All of them are Source of "140.3.230.0" and Target/Destination of "149.104.249.105"
