I'm trying to connect to a website:
i can ping the address:
C:\Users\Ian>ping /6 superuser.com.sixxs.org Pinging ipv6.nginx.sixxs.net [2001:838:2:1::30:67] with 32 bytes of data: Reply from 2001:838:2:1::30:67: time=257ms Reply from 2001:838:2:1::30:67: time=176ms Reply from 2001:838:2:1::30:67: time=161ms Reply from 2001:838:2:1::30:67: time=164ms Ping statistics for 2001:838:2:1::30:67: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 161ms, Maximum = 257ms, Average = 189ms
But neither ping:
C:\Users\Ian>ping supersuer.com.sixxs.org Ping request could not find host supersuer.com.sixxs.org. Please check the name and try again.
But i cannot browse to it (in Chrome or ie):
nor can i telnet to it
C:\Users\Ian>telnet superuser.com.sixxs.org 80 Connecting To superuser.com.sixxs.org...Could not open connection to the host, on port 80: Connect failed
nslookup resolves the name fine, with an authority record and everything!
First we flush the dns, just in case someone wants to suggest it is due to dns caching:
C:\Users\Ian>ipconfig /flushdns Windows IP Configuration Successfully flushed the DNS Resolver Cache.
And now back to the lookup:
C:\Users\Ian>nslookup superuser.com.sixxs.org Server: solo.avatopia.com Address: 10.0.0.98 Non-authoritative answer: Name: ipv6.nginx.sixxs.net Addresses: 2001:838:2:1:2a0:24ff:feab:3b53 2001:960:800::2 2001:1af8:4050::2 2620:0:6b0:a:250:56ff:fe99:78f7 2001:838:2:1::30:67 Aliases: superuser.com.sixxs.org
All those addresses work:
- I can
- I can
telnetto port 80 on them
- I can browse in Chrome (e.g.
http://[2001:838:2:1::30:67]) to them
The name even resolves when I manually call the Windows API function GetAddrInfo.
Why how can I diagnose what
Internet Explorer are doing wrong?
Note: Wireshark is of now help because the dns server (
solo.avatopia.com) is on the other side of an encrypted vpn link; and WireShark refuses to decrypt encrypted vpn traffic.
