NFR Can't access site from home, any IT help appreciated.

  1. Every device connected to the public Internet is assigned a unique number known as an Internet Protocol (IP) address. IP addresses consist of four numbers separated by periods (also called a 'dotted-quad') and will look something like

  2. Referring specifically to IPv4 addresses, and leaving IPv6 out of the equation...

    In fact: anything with is an IP Address used for local loop back.

    The local IP addresses typically used these days by routers are 192.168.x.x.

    And, the local IP addresses typically used back in the day by routers are 10.0.0.x.

    The important IP address with regard to this topic is used by your Cable or DSL modem to connect to the outside world. This IP will not start with or be equal to 192.168 or 10.0.0 and It will be something else dependent on the range your provider is set up to serve.

    Note that x is 8 bits, so up to 256 unique values from 0 to 255. 0 and 255 are reserved, so you really have 254 values available (depending on subnet). The full 4 octets are equivalent to 32 bits.

    Some internet providers use a lease for equipment with a long expiration. So powering down will not help. This is referred to as a sticky IP address and will not renew until the lease has expired.

  3. I'm presently having the same issue, but Ed just keeps wishing me luck. I tried unplugging and restarting the router and it did not work. I'll try unplugging the co-axial line as well. Last year when this happened Chris resolved but would be great if I can achieve a "done it myself" status.

  4. Hey Freestoneangler: try this, just out of curiosity...

    open CMD window (start -> Run -> Cmd)
    in the CMD window enter the following: ping

    You should get back four responses from at IP address

    Let me know if you get said responses.
  5. It does bring up that IP address. Tried ping and it just times out. Flushed DNS, cleared cache and powered down router and unplugged co-ax cable then love. I sent you a PM. Thanks.
  6. I think the one word contest you envoke has banned you from the site using that IP. Just saying. ;)

  7. Hard to believe that with big name players like Ed Call participating...hell, he's nearly doubled his post count on it :)
  8. I notice that Comcrash has a IP address reset function...anyone familiar with this? Perhaps as noted above they use "sticky IP address" and why my power down, disconnect and restart did not work. Sticky IP address...what kind of people dream up such sinister things? :)
  9. Try it. I was going to suggest Hosts file hack with the IP Address hard coded as a stop gap. But I'd try the Comcast reset IP functionality first.

    I like the leased IP address typically. It gives me a reasonable amount of time before I have to rediscover my IP for external access. Yeah, I'm geeky... and my firewall is rock solid settings.
  10. Worst case may be that you could contact your service provider and ask them to reset your router's address.

    The following info is for PC owners. When it comes to Apples, "I know nothing!" (as Sgt. Schultz on Hogan's Heroes would say).

    If you're comfortable at the DOS prompt, you could run tracert to a domain name (like or an IP address if you know one. That will show you the "path" used by your system to get to a site.

    Another diagnostic is to "ping" a site that you know both the name and IP address for. If you can ping the IP, but can't ping the name, there's an outside Name Server problem and there's little you can do other than contact your service provider.

    A methodical "ping" approach for IP addresses is to ping in this order:

    1. First run "iPconfig /all" at the DOS prompt and record your systems IP address and the address of your gateway (internal address of your router). Also record any DNS server addresses if they are different from the gateway address. If you still have a functioning Internet connection, you can get the DNS info from your provider.
    2. Ping your systems IP. This makes sure there's no internal problem in your computer.
    3. Ping your gateway. Now you'll know if your router is up and responding.
    4. Ping all non-gateway DNS addresses. These are provided by your ISP. Due to security configurations they MAY not respond to a ping, but most of the time they will.

    I know it's a lot of tech stuff that many won't be comfortable with, but for those that are willing to try, these things can at least give you more info if you do have to call for more support.
