when I put in arp/d<br>"The ARP entry deletion failed: The requested operation requires elevation. <br>When I tested it intermittently it has seemed to go away. During the time I was writing this initially. Now as of this minute it is still normal looking list of all my IP addresses or mac address. I will keep checking.<br><br>It seems to be coming and going every few minutes dropping my RDP connections and my internet activity or television viewing. I do not know if there is a correlation between the two.&nbsp;<br><br>Does anyone out there know what this might be other than suspicious.

Do you have any vpn connections?

And they are all back.......Yikes what the heck is this? I have a VPN (IPVanish is there name) and I have it on now. I am going to turn it off and see if it stays or goes away...? It is off now and now they are gone. I will wait to try again every few minutes to make sure. I have had the VPN for a year and have noticed all kinds of slow downs and internet issues. I thought it was my provider it was not. Looked at startups nothing there incriminating or resource hogging. Lately this has been worse over the last two months. I thought since I live next to (across the street actually) from one of the best cyber hacking schools in the US. Literally CIA, FBI NSA Government and industry show up hear all the time to hand pick these kids. Hence my concern. I know cause I used to Uber and pick them up at the airport for recruiting camps. Just tried again. Nothing on the big list just the short list.&nbsp;

Terribly sorry on this delay,. Had some other internal issues with WiFi my router and backups. Little scare her. Funny how when a Pandemic occurs and the Technical Support at a major company like ASUS all but evaporates leaves you with major internet connection problems. As of Monday a new firmware is released and suddenly everything works now. Also found some hidden 4th party websites that discovered a series of settings not found apparently on the ASUS site that resolves constant drops and IP renewing functions. When I went by their guidelines I have had the best service from my router I have ever had in the 3 years I have had it. So back to the question.<br><br>I ran the ( netstat -rn ) with VPN ON and OFF. This screenshot may help with the question. I am again sorry this has taken so long to get back. If exposing this image is dangerous for me if anyone were to hack me again which I know they have. I am assuming the VPN is doing something I initially did not understand fully. I am fairly new to using a VPN. I chose IPVanish. So of course not much in the way of tech support right now available so maybe it was I did not understand wha the VPN was doing in the background. If it was sorry for the effort. Hopefully this will benefit someone not to make the same?<br>&nbsp;<br>PLEASE LET ME KNOW IF POSTING ANY OF THESE IMAGES IS DANGEROUS FOR ME TO DISPLAY. I WOULD NOT WANT ANYONE .... HACKERS .... TO SEE THIS AND CAUSE ME MORE PROBLEMS.

This is a great explanation. Thank you sir. I will tell you a funny story actually a couple of them. I have been ordering groceries at Walmart. What I did not realize that when I order from my local Walmart. It says I am ordering from my local store less than 5 miles away in SouthWest Virginia. However the VPN is set to run through the servers as you mention above in locations like Miami, FL Dallas, TX Denver...etc. Guess what keeps happening if I do not turn off the VPN. The order even though it says the order is placed locally. It goes to the Miami Store local to the server there. So I go to pick up. They do not have my order Miami does. I complained to Walmart (It has happened 3 times literally) and they have done something to help stop that. Has not happened since. Anyway I thought I would add since it is a funny story. I have had to reorder all groceries 3 separate times. VPN really works and depending on what store you order from your orders may wind up 1000's of miles away if you are not careful. &nbsp; I appreciate all your hard work and exceptional explanations.&nbsp;

That's really funny and now I hope that everything with vpn technology is under of control :)&nbsp;

Why all the IP addresses on my network?

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.
