What then?

I have a MacBook Pro and I'm running the latest version of Monterey OS and I used thing and it works great. My question is one that I feel I have not seen very much of. Please excuse my lack of knowledge because I'm just now trying to broaden my computer horizons. So after running various tests and scans of my network, I'll get all of this Information. For example: A traceroute and it shows that my computer is nine hops away from the router it's right next to you or I will receive notices that port 8266, 7000, 6161 are open. My question is: What now? Where does one go to find out this information? There are no links on Fing to help me differentiate what is good and what is bad. These are random examples so, I'm not concerned about those questions, but how do I find out where to close ports? Or how many hops is optimal? Or what an NAT-PNP program is?. It's just a small questions that I seem to get caught up on and have found no steady resource please. Can someone help me or guide me the right direction? Please bear in mind that I am new to networking so I would appreciate responses that spell out reasonable answers and not something along the lines of: "well you should go back to school or everyone knows that."

Hi @queenoftheandels I guess that the following is not going to be what you’re looking for & I can only apologise in advance.
I appreciate the frustration of the plethora of abbreviations & general terminology used in networking, especially if you haven’t worked professionally in the industry. So, your questions aren’t small they are very big but reasonable and without knowing your local area network infrastructure & it’s configuration it’s difficult for anyone here to answer.
To get the answers you’re looking for you really need to invest some time researching Local area networks to get some background information on “how things work.” This would allow you to make some value decisions on what you need to investigate & what you can ignore.
Wikipedia is an excellent source of information and this https://en.wikipedia.org/wiki/Local_area_network is a good place to start but it’ll take some time. You can search for terms like “NAT”,“Traceroute”,”PNP” etc which will provide an overview and may be sufficient for your needs & you read as much or as little as you need.
Briefly, open ports are a result of software needing access, for one reason or another, to networks outside of your local network. What needs to be established is what software (or service) is using the port and if it is legitimate.
I hope this will help make a start in finding your answers.0 -

i am gonna make this as quick as I can bc my better is dying, Sorry. I tried Fing on IOS years ago before IOS 11 came out snd it was an Ok-ish tool at the Time, but the limitations of IOS 13, incl forcing the User to Disclose their Info (and Fing Requiring you to login via a User Account which absolutely has far more info than you are aware you’re consenting to release just by posting on the Communit Blog) but… I am a Security and Ethical Nut and Advocate for Privacy and Freedom from Mandatory Uninformed Disclosure.
I am having a little bit of difficulty understanding the exact phrasing of your ? - maybe you used Voice Dictation or are Multi-Lingual? But it’s a little tough to understand exactly what you mean, no offense intended
So, Instead of “Googling” the Port Numbers and Posting Incorrect, Outdated, or Non-Referenced Answers ^^^^ Ahem,
ok, Networking 101 kindergarten Flash Cards:
”The 5,4,3 Rule” (it was IP not even IPV4 when this was first established) in any Contiguous Network, in order to Reduce the Amount of ‘packet Collision’ which would make the Traffic on the Network too ‘loud’ for the Processing Capabilities of Networking Equipment, You can Only use 5 Hubs, 4 Switches, and 3 Routers….. so, let’s say you’re in an…. office ok? So for them to have 9 “hops” that you can See using a Fool (sorry Tool) like Fing, before hardware firewall prevents you from being able to “see” the Next “hop” is several, Many “Hops” if you have a Cable Modem and TV Service from Xfinity or whomever, you will only have One “hop” (your own Router) and it will have a Public IP Address, but the ISP will Not Let you Identify the IP Address of even their Local Office. If you’re seeing 9 “hops” you most likely have a Sateliite TV and Network ISP and the necessity for Privacy is Second to the necessity of QoS “Quality of Service” as for how many “hops” is Good or Bad- would depend entirely on Circumstances that would be a Higher level of Conversation and would include assuming you have knowledge of Hierarchical Networks, Subnetting, Routing Protocols, and those kinds of things- in which case, you wouldn’t be using Fing (or trolling on here providing answers) Truthfully, this is Not the Forum nor Place for Educated individuals to pool their knowledge or answer Questions. Quora or even the Blog of something like Infosec Institute Online IT School will have more answers and they will likely be informed, and not the First Google Hit providing information :/
I’m going to try and give you the Best and z Most Informed Answer I can and to do that I would Refer you to the IANA list of TCP and UDP Ports
two major and important points: One- TCP Port Assignment is “Dynamic” meaning it can change from Month or Year to Year, and A Halfway Decent Programmer or Developer can tweak their Program or App to use an “Assigned” Port Number for something entirely different. Two: when referring to a Port, it is usually ‘assumed’ that the port is a TCP Port amd not UDP (which is Dynamic based on Each and Every Session Connection) but you should state which it is in your Questions and get used to incl that Data
This is the Guide for TCP and UDP Ports there are 65,535 TCP and 65,535 UDP Ports the guide will even list the Registration of the Port, and in Most Cases the Name and Contact of the Programmer, Engineer, Developer, or the Person Responsible for Maintaining the Database of Whomever wrote the Software that’s using that Port
https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml
this is a recent Port Database you can use that is based on “Session”
Here is a Quick article about NAT-PMP or UDnP I suggest also that you search “NAT-PMP” on Apple’s Knowledge Website and learn what it is, and also I’m not Inc a Link bc you should also start to get Acquainted with Searching for Precise and Specific Answers on Forums where the Answers and Discussion are from Educated, Informed, and Knowledgeable Industry Experts whose job it is to convey that knowledge in layman’s terms to all
www Apple Support Communities com
Here is a Different Way of Explaining NAT-PMP
now, simply because I am familiar with the particular Ports you Mentioned, and “Googling” info to Post an Answer is something you can do yourself, so you wouldn’t end up learning anything, and its offensive to see that to me When i have Read ALL 65,535 TCP and UDP port Assignments and kept taking Classes for 8 years since getting my Certs, I’ll break it down:
The TCP or UDP Port being used or in Question, can Only Completely be Accurately Referenced if and when the Traffic from Your IP Address to the “Host” (which could be a Server in Finland) is “Captured” so that it could be Correctly Identified. Port 8000 is a Web Port could be ANY Web page… to identify exactly why and what on your Local Devices established a Connection you would need a Data Packet Capture of the Traffic, which Fing cannot do and is far more advanced then the Answer you’re looking for but the “Session” is part of the Connection that TCP “Transfer Conmection Protocol” is based on
6161: VMware File Server (you either have a BitTorrent Client Program or have Downloaded a File Sharing Program) 6161 is the Most Common “listening Port” for initiating Torrent Downloads
7000: “Open” Port for File Sharing and One of the most Common Open Ports
8299: Unassigned by IANA but, the Closest Assigned Ports:8297,8298,8300 Are All Apple QuickTime Ports
It is very likely for Apps to use a Close Un-Assigned Port if the Connection is bad or traffic is Slow
suggestions: 1: Make SURE that Firevault AND Time Machine Backup are Enabled and that you have either a Separate HD or a Partition to Back Up To!
2: put a piece of tape over your MBP webcam or get a sliding security tab so your Face isn’t always Accessible to any Programs that may have access to the Camera you haven’t Configured Not to, or unaware they can and may use the Cam
3:honestly, I myself will never log into this blog again and have no use for the App. I’m waiting for a meeting and it’s running late but advice in rhis Business is Rarely both Free and Accurate.
most of your ?’s are “CCNA” or Network+ level information, it’s a long journey but Damn the pay is good!
be well
