DNS problems

[Incognitotj]

About 2 months ago I helped build a website that I continue to maintain. It is hosted by www.vskgamingservers.com and the website is www.uzaclan.com. When going to uzaclan, I have been experiencing server not found / dns errors. This has been happening for about a month now. When this happens, other people from around the country and overseas can still get there with no problems. I did a tracert, ping, and used ping plotter - all could not resolve the address.

I have found that sometimes when I can get to uzaclan, I can't get to vsk, vice versa, and sometimes neither of them. Yesterday I could get to uzaclan, but not vsk. While running ping plotter, I noticed the first hop (10.66.192.1) to vsk's ip started suffering some packet loss. This approached and stayed at 100% (see screen cap on my other web site)

http://courses.westshore.cc.mi.us/Sp...s/icannjpg.jpg

About 5 minutes later, I could not access that ip at all, as well as uza or vsk. This usually occurs for about 2 hrs, sometimes less sometimes more.

As you can see from the .jpg, the first hop is to a name server. I have sent an email to res-ip@iana.org but it is too early for a response. I called my isp (Chartermi) and after 1hr 19 min, I talked to steve. Steve didn't know what the term ping referred to. He had never heard of the program ping plotter, and he sure didn't know what the heck a tracert was. Needless to say, no help there.

If anyone can help here I would really appreciate it.

The email for me here is wrong... I usually use Incognito@uzaclan.com, but since I can't get there that won't do much good. If you need to get to me I do use hotmail - twj915@hotmail.com. Otherwise I will check back frequently.

Thanks,

Terry

The #1 problem is that it is a private IP. 10. is not routable on the internet. Note the description in your whois "blackhole" What name server is giving you that?

2 things come to mind

1st- You are running a DNS that THINKS it is autoritative for that domain and isnt.

2nd- They have some DNS sync issues. 1 is giving out correct info, the other is giving out the bad info. Depends on which you hit.

DNS poisioning is possible, but not real likely.

the www.uzaclan.com has DNS entries provided by NS1.vskwehosting.com and NS2.vskwebhosting.com ( per http://reports.internic.net/cgi/whoi...om&type=domain )

Querying NS1.vskwehosting.com for www.uzaclan.com returns 66.165.90.253

Querying NS2.vskwehosting.com for www.uzaclan.com returns with "No response from server"

When using http://66.165.90.253 I always get page not found.

When using http://www.uzaclan.com sometimes I get the website, sometimes I don't. In both cases I check the IP returned for www.uzaclan.com and they are the same. That leads me to believe the problem lies with vks's servers.

I concur with DVNT1. The problem is on the ISP/Hosting servers. your unable to hit the sites with the IP address as they are obviously using hostheaders to allow mulitple sites to use a single IP address (thats not where the problem is) but they are having major issues with their dns servers from what I can see in testing

SJ,

This is being reported by my linksys ethernet router DNS: 24.247.23.40 and 24.247.23.39

Those should be Chartermi's Domain Name servers right? And that is what is first checked whenever you enter a url? Why is that 10.66.192.1 coming up first then?

DVNT,

How did you query vskwebhosting's NS2 and NS1 for www.uzaclan.com. (I want to show that to their tech support)
sidenote: I've been one of bills friends for 3+ years now.

Mntsnow,

Thanks that sounds like something I might be able to take care of (hopefully)

Thanks for your responses guys,

Terry

It does look like ns1 is completely borked and ns2 not answering.

There really isnt anything to take care of for what Mtsnow said. It's standard hosting practice.

Here is what I found with a bit of nslookuping, differs a bit from DVNT1s findings, but they may be doing work on it.

> set type=ns
> uzaclan.com
Server: 10.0.0.2
Address: 10.0.0.2#53

Non-authoritative answer:
uzaclan.com nameserver = ns2.vskwebhosting.com.
uzaclan.com nameserver = ns1.vskwebhosting.com.

Authoritative answers can be found from:
ns2.vskwebhosting.com internet address = 66.165.90.254
ns1.vskwebhosting.com internet address = 66.165.90.253
> server 66.165.90.254
Default server: 66.165.90.254
Address: 66.165.90.254#53
> www.uzaclan.com
;; connection timed out; no servers could be reached
> server NS1.vskwehosting.com
nslookup: Couldn't find server 'NS1.vskwehosting.com': Name or service not known

In a W2k/XP command prompt window run:

nslookup
server ns1.vskwebhosting.com
www.uzaclan.com
exit

nslookup
server ns2.vskwebhosting.com
www.uzaclan.com
exit


btw, siliconjunkie's post also showed the commands he used, the typed commands are shown after the ">"

Or for some other easy DNS tools just check out http://www.dnsstuff.com/

I still have the problem, but I have found a way to circumvent it. I enter vsk's ns ip's in network connections as the dns... works so far

Thanks for the help, and the command prompt info.

speaking of DNS type web tools, here's a good site that will test using many different DNS servers so you can get a well rounded idea of what's seen across the Internet... http://www.mob.net/~ted/tools/index.html
