Strange web site loading/DNS problem

    I've been having problems with the URL's,, and over the
    past week.
    Sometimes the sites load fine, and other times I get "server not
    found". When I can't get to the site, I get the typical traceroute:
    unknown host message (even when using the IP
    address of the site), and here is what I get when the site does come
    up, when using the IP address:

    Traceroute has started ...

    I am normally behind my router, but I disconnected and connected
    directly to the cable modem... and I get the same results. I have also
    flushed my DNS cache.

    I have also changed the DNS server info in my router, to use another
    DNS server instead of Road Runner's. I am still having problems.

    I've also been having problems when sending email to co-workers at Some of the emails make it through, and some don't.
    I switched my SMTP server to our company's, and everything is fine
    now. Before making that change, I was using Road Runner's SMTP server

    I have talked to Time Warner/Road Runner and they don't believe the
    problem is on their end. They let me talk to a tier 3 person, and he
    still couldn't figure it out. He told me to do all of the things that
    I've done... and still no luck.

    Does anyone have any idea what may be causing the problem???
    Can you consistently access,, and/or

    Thank you for any help!

    User-Agent: G2/1.0
    X-HTTP-UserAgent: Mac OS X Firefox/
    I don't 'consistently' access those sites, but I can currently access
    all 3 of them without difficulty. They are all 3 at different IPs, but
    the webserver serving them is configured the same way^1, and the sites
    appear to be developed by the same entity and they all have links to
    each other and they are all domainregistered the same way
    That isn't enough troubleshooting information.
    Traceroute isn't a good tool to start with to troubleshoot in this

    The tool /I/ would start with is grc's IDServe^2, but that isn't
    available for the Mac. But using whatever linux or mac tools you are
    familiar with, I would find out if I had trouble resolving the IP, then
    I would contact the IP over port 80 and see what the IP sez.

    Traceroute is a different thing whose function and strategy I won't go
    into describing here, but it isn't what I would start with for this
    That strategy is useful if you are suspicious of the router function,
    but your troubleshooting would have to lead you there first.
    That is helpful if you determine that you aren't resolving the name, but
    you should demonstrate that with your troubleshooting first.
    But, I'm assuming that your method of sending mails is to use your
    provider's smtp server and the provider is what is having to find out
    that mail for hunger has MX DNS
    which rDNS and which answers:

    220 ESMTP

    .... so that mailserver is currently answering.
    Not yet. What kinds of troubleshooting tools do you have that you are
    familiar with? I don't know Macs at all.

    This part shows that you resolved the name.
    Those hops show you going from your RR network via level3 to ntt & pnap
    where you run out of hop echoes. I can reach the site and my 'ordinary'
    traceroute or ping won't get an echo from the target.

    Where your traceroute stops is based on the nature of the/your/my
    packet. The target IP doesn't answer traceroute or icmp pings. If you
    were going to see a traceroute reach the target, you would have to be
    using a traceroute tool which used tcp port 80 echoes.

    Here is the result of such a tool:

    6 (
    7 (
    8 ( [open]

    <I snipped the times to prevent wrapping and confusion>

    .... which means that those are the tcp hops, as opposed to the udp or
    icmp hops.

    Notice that the tcp hop 7 above is the last traceroute hop #13 you saw:

    <fireb traceroute> 13

    What is the big deal? The OP is a GG poster, which stamps the NPH of
    hir IP.

    People who don't want to expose their IP should be using a newsagent and
    a newsserver instead of GG and they should be using a newsserver which
    doesn't stamp an NPH line.

    Your own newsserver stamps your IP in the NPH which shows you to be
    accessing via sbcglobal via DSL which is in the neighborhood of
    Kalamazoo MI US.

    If you don't like that, then you should be posting your usenet messages
    via a newsserver which doesn't do that. Personally I don't think it is
    a big deal.
