Can't access some websites -- same domain different subdomain

  1. There are some Japanese flash game websites on a domain called web.fc2.com. I can access some but not others, getting a timeout error.

    I can't get to ancho.web.fc2.com and detarou.web.fc2.com . I can get to pi3141592c147.web.fc2.com and yoinouchi.web.fc2.com . I've pinged all four and get very similar results - I know 'similar' is not 'exact' but I am not techy enough to read/understand ping results.

    A possibly relevant pair of messages I get from pinging via dnsstuff.com are
    - The destination appears to block unwanted UDP packets.
    - There appears to be a firewall at <ip address> (hop 1) that blocks unwanted TCP packets.

    Both my windows xp and my ubuntu box have the same problem, so it's not a hosts file issue or a system based blocking software. Might be my router?

    Thank you...

    Might I ask what browser you are using? Using my Google Chrome, I can access http://ancho.web.fc2.com/ & http://yoinouchi.web.fc2.com/

    Pick your browser. Firefox, Chrome, IE. Doesn't work on any. :(

    Gosh, I don't know. Does time of day matter? Other than that, I have no idea & wish you well.

    I can access this
    and this too
    so can I

    so it is not website dependent, but localized to
    a) your systems OR
    b) your ISP​

    Hi Jobeard, here is what I get on the nslookup and the traceroute. Since it happens on both computers it must be the router or as you suggest my ISP. What must I do to fix?

    the RED stuff says your router(modem) is not correct
    OR your TCP stack is a mess,
    but how it found the Address: 208.71.106.61 is amazing.
    We'll need to work on that.
    Code:
    1 2 ms <1 ms <1 ms 192.168.0.1   <<YOUR ROUTER ADDRESS
    2 14 ms 14 ms 14 ms adsl-99-58-75-254.dsl.pltn13.sbcglobal.net [99.5 8.75.254]  << YOUR ISP GATEWAY ADDRESS
    3 15 ms 14 ms 13 ms dist2-vlan62.pltnca.sbcglobal.net [99.36.71.2]  <<STILL inside your ISP
    4 * * * [COLOR="Red"]Request timed out.   << first node outside your ISP[/COLOR]
    5 * * * Request timed out.
    the network beyond your ISP is questionable, but let's fix the router/modem and do this again.

    Using an Admin login, get a command prompt and enter
    Code:
    netsh winsock reset catalog
    netsh int ip reset c:\resetlog.txt
    1. Disconnect the system from the router
    2. Power off the router
    3. reboot the system and while waiting for it, power on the router
    4. login again and then connect the system to the router
    Now get a command prompt again and run IPCONFIG /ALL >MYTCP.txt
    follow-up with a copy/paste of mytcp.txt contents . . .

    that's perfect; try these - - your results should look like the BLUE data
    Code:
    [B]nslookup google.com.[/B]   <<note trailing PERIOD
    Server:  dns-cac-lb-01.rr.com
    Address:  209.18.47.61
    
    [COLOR="Blue"]Name:    google.com
    Addresses:  74.125.224.146, 74.125.224.147, 74.125.224.148, 74.125.224.144
    	  74.125.224.145[/COLOR]
    
    [B]nslookup yahoo.com.[/B]    <<note trailing PERIOD
    Server:  dns-cac-lb-01.rr.com
    Address:  209.18.47.61
    
    [COLOR="Blue"]Name:    yahoo.com
    Addresses:  69.147.125.65, 72.30.2.43, 98.137.149.56, 209.191.122.70
    	  67.195.160.76[/COLOR]
    
    [/COLOR]
    
    then try this to each one:
    Code:
    [B]tracert google.com[/B]  << MISSING THE TRAILING PERIOD[B]
    [B]tracert yahoo.com[/B]
    
    AND FINALLY, try
    Code:
    [B]tracert ancho.web.fc2.com[/B]
    again
    We are looking for the * * * Timeouts and if you see any in the path, COPY/PASE the whole tracert data . . .

    My nslookups are different ... :/
    Is it looking to 192.168.0.1 as a dns server? Because I don't think that's right...
    Code:

    Yes that IS right, but it's indirect. NOTICE the ipconfig data shows
    Code:
            Default Gateway . . . . . . . . . : 192.168.0.1
            DHCP Server . . . . . . . . . . . : 192.168.0.1
            [B]DNS Servers . . . . . . . . . . . : 192.168.0.1[/B]
    
    that is very common.
    The action for a DNS request on port 53 received by the router is to just forward it to the WAN port connected to your modem and then to your ISP where it gets resolved.
    This can be corrected, but would not appear to be YOUR issue.
    did not effect the results; your times on line 5
    Code:
    5    15 ms    16 ms    15 ms ...
    are very typical
    my nslookup google.com.
    Code:
    Addresses:  74.125.224.[B]146[/B], 74.125.224.[B]147[/B], 74.125.224.[B]148[/B], 74.125.224.[B]144[/B]
              74.125.224.145
    differs only in the last octet (ie three digits) from yours
    Code:
    Name:    google.com
    Addresses:  74.125.224.[B]115[/B], 74.125.224.[B]112[/B], 74.125.224.[B]113[/B], 74.125.224.[B]116[/B]
              74.125.224.[B]114[/B]
    
    Using another network tool, I find the Google owns
    Code:
    NetRange:       74.125.0.0 - 74.125.255.255
    CIDR:           74.125.0.0/16
    which means it has everything in 74.125.*.*
    so your nslookup is returning good results.

    I can perform tracert ancho.web.fc2.com all the way and get the final Trace Complete without any timeouts.

    Got to go for now - - - if you have the time google for Black Hole Routers and Setting MTU. Will discuss with you asap . . ..

    Good to know about the 192.168.0.1 and DNS - I am learning a ton here thanks to you. I also will be away for the day but will google for those this evening. BTW, had to reboot the router this morning to connect wireless, not sure why.

    3/31/11
    I took a look at the routing table. Does that entry for 192.168.0.0 mean anything?

    Code:
    Destination 	Mask 	Gateway 	Metric 	Active
    76.254.15.254 	255.255.255.255 	0.0.0.0 	0 	Yes
    192.168.0.0 	255.255.255.0 	0.0.0.0 	0 	Yes
    0.0.0.0 	0.0.0.0 	76.254.15.254 	0 	Yes

    Hate to do this, but -- bump.

    Code:
    Destination 	Mask 	           Gateway 	     Metric 	Active
    76.254.15.254      255.255.255.255  [COLOR="Red"]0.0.0.0[/COLOR] 	     0 	Yes[B][1][/B]
    192.168.0.0        255.255.255.0     [COLOR="Red"]0.0.0.0 [/COLOR]	     0 	Yes[B][2][/B]
    0.0.0.0             0.0.0.0         76.254.15.254    0 	Yes[B][3][/B]
    [3] is the default route; notice ip/mask is as broad as it gets
    [1] is an example of the most specific route; one address and the mask says that's all yoiu get
    [2]is routing for anything on your LAN

    the output you show is different than mine and the 0.0.0.0 entries for gateway are puzzling

    I got a new computer with Win7. Still am unable to get to the sites listed.

    This is my route print - somewhat lengthier than yours. There are entries for IPv6 but I edited those out.

    Should I attempt to edit my router's table?

    leave the routing table alone

    use google to find disable ipv6 and apply the win/7 fix

    I don't mean to question your expertise, but is that really necessary? The problem still exists on the Ubuntu box and of course the WinXP laptop. IMHO IPv6 is or should be irrelevant to the problem.

    jobeard TS Ambassador Posts: 13,426   +317

    question all you like - - that's how we all learn.

    Our routers just don't handle IPv6 yet. Linksys is just terriible and few really work.

    We can't shutdown IPv6 in the router per se, so we make sure our systems only
    make IPv4 requests.

    Then too, all the reasons for using IPv6 are targeted for the Internet Backbone or
    hugh companies like GM, IBM, Verizon where there's far more system internally to the domain.

    Think about it; our person home system NEVER have 253 devices attached
    (the limit for one subnet), so why do we need to coerse IPv6 into a subnet with only 5-6 devices?

    True, it can't hurt.
    I followed instructions at http://support.microsoft.com/kb/929852. Went without a hitch except when they said "type 0xffffffff" they meant "type ffffffff" (it displays 0xffffffff when done). Rebooted and all is well.
     
  22. jobeard

    jobeard TS Ambassador Posts: 13,426   +317

    BINGO! yea that 0xffff vs ffff can be misleading, but the issue is to but
    a binary all-ones into the field, aka ffffffff

    You'll do fine from here :)

    OK, so back to my original problem now?

    I've read http://support.microsoft.com/kb/314825 about black hole routers and an article about MTU at http://groups.google.com/group/blogger-help/web/how-to-check-the-mtu-setting-on-your-computer?pli=1.

    Tried pinging ancho.web.fc2.com with different packet sizes but same results:
    Code:
    C:\Users\fallinghawks>ping 208.71.106.61
    
    Pinging 208.71.106.61 with 32 bytes of data:

    Approximate round trip times in milli-seconds:
        Minimum = 26ms, Maximum = 27ms, Average = 26ms
    retry your packet size by reducing it by 32 (1472 - 32 ) until you reach the site address. Then set that as the MTU into your router (fixing all attached systems)
    or in your own system using Regedit

    In the first example, even 32 doesn't work.
