Your ISP I assume. So that is just you doing or trying to do a dns query. Your stupid 'firewall' in your router is logging it as something its not. Many routers allow port 53 (UDP and TCP) on the WAN port the router to be portmapped to port 53 (UDP and TCP) on the inside of the router itself, exposing the.
I just wrote out a lengthy, detailed story about what is going on, and then when I went to post, I had apparently been logged out and it said I didn't have permission. So I'm going to try to summarize. I greatly appreciate any help someone can shine on this.
I am getting bursts (about 20-30) of pings from an outside address ( 3.0.1.128 ) with a destination of 28.164.4.176. The source appears to belong to General Electric in Fairfield, CT. The destination appears to belong to the Dept. of Defense Network Information Center in Columbus, OH. It looks like for some reason, my and my fiance's iPhones (6, up to date on software, no jailbreak) are randomly being assigned that 3.0.1.128 address and that is when the pings come, and we occasionally lose connection. I have a Netgear 3000-100NAS modem/router. I have exchanged the gateway, to get a new MAC address, to force my ISP to issue a new public IP. The problem continued after this. The phone that gets the IP seems completely random. I am also being port scanned by Comcast's DNS. These pings are occasionally knocking us offline, and then it reconnects. The phone that picks up the address is seemingly random, but never both at the same time. Then after a few minutes they pick a local address from the DHCP.
I blogged about this in March 2018 (Some routers can force their DNS. An option on the Speed Guide Security Scan lets you scan any port for TCP, UDP or both. No hacking was needed, the owners of many Netgear routers do not change.
On our network we have 2 laptops, a xbox one, a roku, and then our two smartphones. I basically just left out all of the story telling and dealing with customer service, etc. If there is anymore information I can provide, I will be glad to. I really hope someone can help.
With some games and applications, it may be necessary to open one or more ports or setup port forwarding on your home router. Below are the steps required with most routers and additional help and suggestions with troubleshooting issues that may be encountered.
WarningPorts are often closed on a router to help prevent unauthorized access to your home network. Opening any additional ports on your router may decrease the overall security of your network.
NoteIf you want to open ports to give access to a game or an application like BitTorrent, make sure it is absolutely necessary. In some situations, it may be a firewall on your computer or router that is blocking access. Try temporarily disabling your firewall to make sure this is not the cause of your problems.

Referring to the following picture as an example, with single port forwarding, you have different fields that need to be completed.
First, the Application Name is the name given to describe what the ports are that you are opening. In our example below, you can see this router has drop-down menus and empty boxes. If you are opening a common port such as FTP, selecting that option enables that port. However, in most situations, you need to type the name of the application. For example, you would type in the name of the game.
Next is the Externet Port and Internet Port. Enter the port you want to open in both of these fields. For example, if you were opening port 88, you would enter 88 in both boxes.
Next is the Protocol, which is often able to be either TCP, UDP, or both. If you are uncertain of the exact protocol needed, use both. If you do not have a Both option, create two open ports for both TCP and UDP.
Next is the To IP address, which is the IP address of the computer or networking device this port is being forwarded to on the network.
Finally, once all these values have been configured, check the Enabled box and click the Save Changes button.
If your application or game requires a range of ports, such as 6112-6119, your router should have a Port Range forwarding section like the one shown below. In this section, you would follow the same steps as those mentioned above, however, instead of entering an individual port, you would enter the starting and ending port number. For example, if you were given instructions to open port 6112-6119, you would enter 6112 as your starting port and 6119 as your ending port.
Finally, if after enabling port forwarding you are still encountering issues with another computer or application seeing your computer, it may be necessary to enable DMZ. Often this setting is in the same area of the router configuration as discussed above and can be changed from disabled to enabled.
There are several services that can test if your new opened port can be seen. We suggest trying Canyouseeme and the port checker tool from Portforward.
