Speakerfritz Posted August 21, 2015 Share Posted August 21, 2015 So my internet connection is wonky for some reason. It only works here and nowhere else. Never had this problem before. It either worked or it didn't. Now my access seems to be the first site and I go to and that is it. How does it work anyway? How do all those servers shake hands and get all these people where they want to go? all servers on the internet register their IP addresses and DNS names on a handful of DNS servers. The DNS servers exchange their database info when you login into your computer, your PC gets and IP address from your ISP, that IP address also contains which DNS server you will be using when you type in a URL, you are entering a DNS name+a start web page your PC operating system does a DNS request and gets an IP address corelation at the transport layer, your PC sends packets with destination info that contains the target IP address the packets have your host IP address and servers as the return address for return packets in between you and the destination web page are whats refered to as hops hop 1 is your router in your house, to the router at the other end of the local ISP connection local routers hand off to regional one on the destination side, you wind up passing thru the destination servers ISP which involves theire regional and local routers...then their gateway or border router, then the link into the data center these all have IP addresses so basically, DSN gets your PC the IP address translation, the transmissions have headers and context info that says where the packet should go, who sent it, etc. as packets pass thru the hops, each device sends an acknolwedgement to your PC that the packet was recieved. If a destination gets a packet out of sequence, at retry command is sent to the sender to send the packet again. once all packets get acknoldged as recieved, the next packet is sent. about 5ms per hop, per packet. so the core control process is the DNS tables along with the packet send, ack, recieve transmissions along each hop. 1 Quote Link to comment Share on other sites More sharing options...

wvu80 Posted August 21, 2015 Share Posted August 21, 2015 (edited) ATT tech just left and my twisted pair was bad, also two bird nests in the cross box (12,000 ft away), and lastly my modem had crapped out. My signal to noise ratio now a whopping 28 db. Right now I have the best internet service ever. What is your speed? I run this occasionally to make sure everything is up to spec. My usual numbers are 9ms ping, 50 down, 5 up. http://www.speedtest.net/ Edited August 21, 2015 by wvu80 Quote Link to comment Share on other sites More sharing options...
JL Sargent Posted August 21, 2015 Author Share Posted August 21, 2015 That's fast. I'm only paying for 3Mb/s down and I've got 3.1Mb/s down per that test. Being 12,000 ft from the cross box makes me ineligible for U-verse which can get you up all the way up to 100 Mb/s. Quote Link to comment Share on other sites More sharing options...

JL Sargent Posted August 27, 2015 Author Share Posted August 27, 2015 It would be interesting to know what you pay for your internet service and how fast it is. I pay: $47 per month for 6 MB/Sec down and 300KB/Sec up. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted August 28, 2015 Share Posted August 28, 2015 Boy Carl, that is quick! Too bad my home isn't like that. Here we have a business cable account. Quote Link to comment Share on other sites More sharing options...
