After clicking some Googe Ads and leave the ads site or delete the tab, your browser may forwards you to other site which may give you message such as "Congrulation,! You Get Prize, Bonus, Coupon.etc" Probably your browser is infected by virus and the Congurlation site is hacker /attacker virus site.. I will think the following methods to solve my problem, Please advise those methods are correct 1- Right away or now, remove the forwars site(Congrulation site) or delete such browser Tab 2- Look at this image: https://computer28.com/image/deletecache.jpg Delete or clean your chrome browser data At Chrome browser, Click Sitting->Privacy Security->Delete Browser Data, it will pop up window, in that window, Click Advanced->Select Time Range(All Time)->Tick all box below Time range such as Browsering History..etc. Click Delete Data button 3-If using Window 10, Turn on Microsoft Defender Virus Protection System, always turn it on https://carleton.ca/its/help-centre/how-to-enable-windows-defender-on-personal-pc/ You are better to install Microsoft Window 11 if u are using WIndow 10 4- Add X-Content-Type-Options: nosniff on header at my apache server

Visitors or users may open many page of website to get streaming data ,and they want to open many browser tabs to read different data. That will depend on your Laptop or mobile capiblity how can handle many new socket.io to run on multiple tab at the same time, If limited computer resouce or memory, you will be limited for number of browser tabs display.If u use socket with Redis /stream event that allow display directly into html page tab (just type https://yourdomain:5051/stream on address bar) or throught javascript parse data into html page but it may only allow 3 tabs running on the same time.How you can run it on many tabs ?-----------------------------------------------1-You can use localStorage(getItem or setItem) to share information between browser tabOr...you can use2-window.addEventListener('blur', notstream);window.addEventListener('focus', stream);When the user not read or not focus the tag, close the streaming socketio, then Whenthat users want to read it again and focus the tag, reconnect the socket. We know users only can read 1 tag at a time only,function notstrem(){souce.close();//close the socket.io}function stream(){//user focus the tab againrefresh();// re-run that funation u can stream data before}function refresh(){//Redisvar source = new EventSource("https://yourdomainsocket-site.com"+":5051/stream"); source.addEventListener('publish', function(event) {dataextract(event.data);if (typeof ws=='function')ws(event.data);if (typeof updatechart=='function')updatechart(event.data); }, false); source.addEventListener('error', function(event) { }, false);return source;}let source=null;jQuery(document).ready(function($) {console.log("onload");source=refresh();});

Topic:
Network Routers;Networking Hardware;Network Operations
Recently, I am taking tutorial of network class and there are a lot of network concept
i am getting confused, so I try to start to understand my home PC and network to solve my network concept problem.
At home, I get two PC with one at window 7 and the other at Window XP which is connected to one device we call ADSL something like the photo I include at web link
https://en.wikipedia.org/wiki/File:Adsl_connections.jpg
When I go to broadband internet, I log into window 7 or PPPoE connection utility or
software with my login and password that is provided by my ISP company
After connection, I try ipconfig on cmd.exe,and I got the following message
PPP adaptor:
Ipv4 IP 219.77.x.x
subnet mask: 255.255.2555.2555
default gateway:0.0.0.0
I am using auto configuration mode for the connection setup for external IP and internet .
The question:
1- the device of ADSL means that is router plus modem, Right ?
2- router means network switches like the 4 ports in the photo attached, Right ?
3- DefaultGateway or Gateway for my case that is refered to the my ADSL router, RIght
4- Why the default gateway is 0.0.0.0 ?
5- I google default gateway 0.0.0.0, and found one article how to delete 0.0.0.0 default gateway (http://www.shayanderson.com/microsoft-windows/windows-7-fix-0-0-0-0-default-gateway-issue.htm) but it doesn't work, but 0.0.0.0 is still there,why?
6- I also tried to use the command
netsp int ip reset c: esetlog.txt & netsp winsock reset c:winsock.log and reset the computer and logging again, but 0.0.0.0 is still there and not deleted, why ?
Hope you write more like for teaching student in a class for those questions
Please advise
Duncan

You have nothing to worry about if you are able to get on the internet.
Going back to your question
0.0.0.0 in network statements for routing just means send everything that has no specified instructions to the gateway.
I'm using non-technical terms for simplicity.
Open command prompt and type
"route print"
then press "enter"
You will see router statements. The 1st address at the top shows 0.0.0.0 0.0.0.0 the IP address that follows is the gateway for that computer. It could be a public address or private depending on if you are using public or private addresses internally

Your modem handles DHCP (giving private ip numbers to your internal network), so dont worry about that setting being NO, it just means the device you use to make the PPPoE connection is not configured as a DHCP server, no problem.

open command prompt and type
ipconfig /all
Private addresses eg 192.168.1.1 are not allowed on the internet. They are not routable and are dropped by ISPs. Don't pay too much attention to this to avoid confusion. Private addresses need NAT to translate them to public IP Addresses.
Consider a building for example with a lot of rooms.
eg Room A, Room B, Room C etc.
Many buildings may have the same Room number normenclature in them. You can not send a letter to Room A. Post office does not know where to send it.
Room A, B and C are private addresses
Your public address would be the address of the house, eg 555 Heaven Street, Paradise City, Universe

Yes understood the term of gateway
the ADSL device is gateway to ISP
ISP gateway is gateway to internet
Anyway,
how to enable DHCP or let it "yes" ? So I can get back default gateway setting

Hello again,
No, please see the gateway as a mean to connect to the internet.
Since you are directly connected you do not have a gateway YOU ARE the gateway.
If your modem is logged on to your ISP it gets an public ip and probably 2 DNS servers assigned, thats it.
When you connect to the internet (through your modem) then you are using the modem as a gateway. (remember, it is a mean to go to the internet)
Same with larger networks, they probably have multipl connections to the internet so possibly mulitple gateways.

Dear AKinsd,
Public address mean 203.218.x.x. that is internet IP address, Right ?
my ADSL router is gateway, Right ?
There is no private IP address for my case, I just get etherent IPv4 Ip address, only
So what you mean for private IP address, please write it in techincally

Your ISP is your gateway to the internet
Your router is your gateway to your ISP.
It's like going through your front door and through your main gate to the street.

Dear Patricksr1972,
You mean, actually, there is no default gateway for my case since I am using PPPoE
connection(point to point). THe gateway is ISP itself. SO users of ISP just need
directly connect to its gateway throught the modem at my home with login and password
that it is.
The default gateway is descibe the internal LAN larger network like it at Univeristy,
something like that
IS it right ?

Nothing to worry about then. Just ignore the 0s
That means the public address is your gateway.
On your computer, do a show ipconfig /all
That will give you your private ip address and your router will be your gateway.

No
You need to set DHCP to YES.
That is the reason you're getting the 0.0.0.0.
It's not sending a request (ARP) out to your ISP.

DSL is just the term for the type of service you have.
Replace DSL with "Fast Speed Internet".
It will sound odd to look at your router and say that is my fast speed internet.
Similar to looking at your cooler and saying, that is my fountain water. You can put any type of water or juice in your cooler. The content does not change what your cooler is.

Hi mister Hong Kong :)
You show us: Ipv4 IP 219.77.xxx.xxx ( i obfuscate so we do not see your public ip)
default gateway:0.0.0.0
This means the connection to your provider, it does not need a gateway because IT IS the gateway.
1- the device of ADSL means that is router plus modem, Right ?
Yes thats right
2- router means network switches like the 4 ports in the photo attached, Right ?
It surely looks like a router but could also be an Access Point.
3- DefaultGateway or Gateway for my case that is refered to the my ADSL router, RIght
Default Gateway is the (internal)ipnumber of the device that connects to your provider
4- Why the default gateway is 0.0.0.0 ?
Because there is non.
Hope this helps

Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data ...
Router is not a Switch. A switch switches packets
A Router routes packets
Default gateway is like the main door of a house.
To go out of the house, you need to go through the main door, otherwise, you'll just be going from one room to another
Your public gateway is the IP Address of your ISP that your network is assigned to. Usually this is populated by their DHCP server. If you're getting 0.0.0.0, you may need to contact your ISP for resolution. Maybe reset your modem.
The netsh command only resets the NIC interface on the computer you ran it on. The issue you're having seem to be on your modem. Most modems have a reset button that you can poke a pin to and hold for about 10 seconds.
