Internet Protocols

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.

I am seeking a program that will constantly monitor active internet access for me. I need it to check at programmable intervals to make sure the net is available. I would want to set mine for a check every minute or so. I am having difficulty with my isp going off for up to two minutes several times a day without warning. I need the program to be free or shareware. There are MANY available but would prefer  a personal recommendation from an Expert that has had personal success with the program personally. Can any Expert recommend one to me?

I have a 6 year old Lenovo Ideapad P500, 6 gigs of RAM running Windows 10.  I have a dedicated gigabit internet connection (1000 down/1000 up).  I connected the laptop via CAT6 cable directly to my modem.  However, when I speed test it, I am only getting around 90 down/90 up. I have 2 younger computers on the modem directly connected and they speed test perfectly. I know it is old, but is that fact holding it down?  I have only the essentials installed on it, so it is pretty clean.  Anti-virus sweeps show it to be clean as well.  What other checks/tests/troubleshooting can I perform?

the internet here will go out for 5 - 10 seconds several times a day.

Wondering if there's anything you can see that's a problem or just a loose connection on the pole somewhere (and how likely will they find it?).

I was using a new netgear docsis 3 modem and having this problem.
Got a Cablevision supplied motorola docsis 2 modem and put that in and problem continues
theres only the cable modem on the coax. No TVs.
Connections I can get to - both sides of the lightning arrester / grounding tap outside and the cable connection onto the modem are tight and cablevision installed connectors.
i set up to ping 1.1.1.1 -t.  It'll go on for a while with time of 10 - 15 ms.  then it'll just stop for 5 - 10 seconds.  Then start back up with 10 - 15ms.
I was getting similar error messages on the netgear router, now these messages.  I'd think any systemic / DHCP address problems would have the connection be out completely, not for 5 - 10 seconds every once in a while. But are these errors indicative of other issues?

I called cablevision and they poo pood their old surfboard modem. So I put the netgear back in the network.  Got the errors in the last picture.  And internet went out for minutes and I rebooted the modem and it came back up.

There's a picture below of the signals at the netgear and it has a 6db attenuator in it. the rep said signals are ok / better with the 6db in there than without it.  But the uncorrected errors?  the outage needing a reboot?  And the …

Hi, My SEO team is having me create directories for certain keywords, like /affordable-meal-delivery/, so that the URL is mywebpage.com/affordable-meal-delivery/

The only way I know to do this is to create the directory and then have an index.html inside the directory. But I don't like having so many pages called index.html, for one thing I am afraid of overwriting one to another.

This site is able to do it without an index.html: www.freshnlean.com/gluten-free-meal-delivery/  - if I add index.html to that, it goes to a page not found.

We are on an Apache server. So it looks to me like this:



But I have ten or so of those directories with an index.html in each. How can I do this without the index.html. Ideally, I would want the page inside the directory to be affordable-meal-delivery.html. Can I use an htaccess file to do this?

Thanks.

I did a speed test from several speed test sites for my 1 gig Internet circuit and my download and upload are so different. The upload seems fine but the download is so off. It never passes 250Mbps. I have another 300 Mbps with another ISP and when I tested it with the speedtest sites, the download and upload are almost the same, around 250Mbps.
The tech was onsite and tested with his test set and he said that he gets around 900Mbps upload and download.
How do I explain this? Can I trust the 1G circuit provider? What is the explanation for the speedtest sites reported big differences between download and upload.

Any thoughts? Thanks

Internet through Cable line or Satellite

I have read online that there are fiber cables ran through the Oceans to reach other continents in order to provide internet connection.
I have also read that internet connection is provided through Satellites somewhere in the Orbit, and there is no need to run cables from one end of the globe to another.

I am not sure which approach is used to have people in the world connect to Internet.

Any Expert to shade some lights on this ?

Thanks

Simple way to monitor the internet connection to a remote server.
I would like to monitor the internet connection to several remote servers and then be notifed via email if the servers are offline.
Or alternatively. I would like to monitor 1 static IP to see if it is active on the internet (which should tell me if there is internet at the remote site).. and send me an email when
that IP loses internet ...
Is there a way to do this?
If yes, what do you suggest?

When you type in experts-exchange.com in a web browser, theres all the work of resolving the name into an ip address and then your packets are sent from your computer to the EE web server and vice versa, going through routers around the web, right?

Contrast that with an email?  I was explaining to someone that large attachments in an email might cause the email to not be delivered as it routes its way through the web. Then I wondered... is the email actually going through  mail servers on the web and being reforwarded? Or just routers (on the backbone?). If it's just routers, do they actually care how big the total email is? It's just a lot of packets being sent in the same direction.

ie - is there really a limit to an attachment size limit in email OTHER THAN at the sender or receiver email server?  Yes, the sender server or receiving server can set limits to the size of the attachment.  But after resolving the MX record and sending to the receiving server.... what could get in the way?

THANKS!

When click on an email link in Internet Explorer, it does not open the default email program, but a new page opens up asking to add an email account instead.   Can this be fixed so that the default email program is opened?

Dumb question.  Do the companies have to register their domains based on their country code?  For example, if my business in Canada, do I have to register as company.ca ?  What prevents me to register as .com?

I have been doing some research into setting up redundant ISPs on the PANs (Palo Alto firewalls), and it seems that if we don't want to run BGP for that site, the best alternative seems to be PBF.  Am I on the right track with that?  Are there other alternatives?

Hi,

We have a Windows 10 PC connected via a wired ethernet connection to our router.

To test the stability of this ethernet connection, we have run a continuous ping test via command line.

One of the results back have displayed that 1 out of 4 packets were lost (25% loss).

This test was initially ran to test for disconnects or problems with the wired internet connection.

What is the significance of the ping test and how does the 25% loss reflect on wired internet connection for this PC?

Thanks,
Robbie

Issue #1: I currently have 1 gig Internet speed (service) from my local cable provider BlueStream.  For months I have had an annoying intermittent problem with their service.  There are times when the service will completely go down multiple times in one day, but each time it goes down, it may be for only 1 or 2 minutes and then it right back up as if nothing had happened.  The modem did NOT reboot, perhaps the indicator light may go out and back on, but that's it.  This happens about 5 or 6 days per month, sometimes more.  

Issue #2: The second issue is when I go to ANY random site, the web page will NOT load properly or not load at all.  However, as soon as I hit F5 to reload it pops right on in a millisecond.  I get this on 3 different browsers, Edge, Firefox and Chrome.  I have tested my connection MANY times using http://www.dslreports.com/speedtest and usually the tests results are very good to excellent. BlueStream has been out to my home 5 different times for these issues.  I am on my 4th modem and two different models.  They have also rewired the outside lines and checked most everything outside of my house.  Nothing has fixed this issue.  

In contrast, I disconnected my ethernet connection and reconnected to my internet hot spot on my iphone and at only 8MB/s I was loading pages faster with no problems as I outlined in issue #2.

By pure luck, the last time they were out they actually SAW this problem "live" for the first time (Issue #2) and saw it happen.  …

Hello,

For about a week now, Google defaults to Germany and our ISP (G3) investigated their settings and said they’re all correct.
 
We’re a little stumped as to the cause and need some help troubleshooting.

Hello EE,

Our VPN firewall prevents ipV6 (blocks) so our Visual Studio debugger is failing to connect.
I wonder if anyone knows of a way in Visual Studio to turn off ipV6 and only use IPv4.

I upgraded my manager's computer to Windows 10. The manager has at least 50-60 desktop web links. Now in windows 10, each web link take 20 - 30 seconds t load the page. I have reset IE to defaults, changed the default browser to edge (the links still open in IE). uninstalled / reinstalled .net4. Set the file explorer to defaults. no add-ins. Can't figure out the issue.

I get error below...

I was working earlier today.

Can not  access from any chrome and firefox as well.

TLS 1.0, TLS 1.1, and TLS 1.2 is already turned on in IE. Tried removing it and adding back in but no luck.
Server is : Windows Server 2012 R2

Error below

This page can’t be displayed


Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://www.virginaustralia.com  again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details), which is not considered secure.

The proxy server would always get reset to (127.1.1.1) port 8003 in IE and if you manually set it back to no proxy and delete the line item out on a restart it will automatically re-enable itself. We do not use a proxy server and this address is not a valid one. I did read online about it: (http://deletemalware.blogspot.com/2014/12/remove-proxy-settings-127001-hijack.html)

followed the steps but after a reboot it will always come back.

Thoughts>?
