This is my pop mail server. I can't reach it using TCL's DNS but when I switched to OpenDNS servers I can reach it. This is the first time this has happened. Just wondering if those who are using 203.96.152.4/12 as their DNS servers also have this problem?

Thanks

Not working for me on the Paradise DNS servers.

Have you tried the Clear ones? Most people seem to be using these now as they don't seem to have as many issues.

Hmm - then it must be Paradise's DNS servers. OpenDNS worked. I will also try Clear's.

Thanks for the feedback. This is the first time it's happened so it's a bit strange.

Whoops -I can't find Clear's DNS servers - any idea what they are?

Thanks

Working fine on Clearnet DNS (203.97.78.43 and 2203.97.78.44). You shouldn't use the Paradise servers.

Thanks - that also worked and I put it into the router. I have been using Paradise's DNS ever since I have had TCL cable and it's never had a problem before. Oh well - I trust this lot is better.

Hmm... my router is still using the Paradise ones. Will change them to the ClearNet ones now.

Is the problem ping, or name resolution?

The two are seperate thing.

I'm on TCL and can resolve and ping the resolved address:

PING pop.1and1.com (74.208.5.5) 56(84) bytes of data.
64 bytes from pop.perfora.net (74.208.5.5): icmp_seq=1 ttl=48 time=203 ms
64 bytes from pop.perfora.net (74.208.5.5): icmp_seq=2 ttl=48 time=204 ms

Audiophiles are such twits! They buy such pointless stuff: Gold plated cables, $2000 power cords. Idiots.

OOOHHHH HYPERFIBRE!

The problem is name resolution with the Paradise DNS servers (203.96.152.4, 203.96.152.12) - which DNS servers are you using?

Well, I'm a muppet (thus my nick)

I've setup a caching DNS server at home and forgot all about it.

It works fine, as I posted:

micro% dig @localhost pop.1and1.com

; > DiG 9.5.1-P3 > @localhost pop.1and1.com
; (2 servers found)
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 61296
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 0

;; QUESTION SECTION:
;pop.1and1.com. IN A

;; ANSWER SECTION:
pop.1and1.com. 6922 IN A 74.208.5.5

;; AUTHORITY SECTION:
1and1.com. 172521 IN NS ns91.1and1.com.
1and1.com. 172521 IN NS ns92.1and1.com.

;; Query time: 22 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Thu May 6 21:50:55 2010
;; MSG SIZE rcvd: 85

However, you're right, querying the Paradise DNS server fails:

micro% dig @203.96.152.4 pop.1and1.com

; > DiG 9.5.1-P3 > @203.96.152.4 pop.1and1.com
; (1 server found)
;; global options: printcmd
;; connection timed out; no servers could be reached

The strange thing is it has worked for year and only failed tonight. When it happened I called tech support for my web hosting (which landed me in the Phillipines!) and they said they could ping the server fine. That suggested to me that it was a DNS error and my then trying OpenDNS which worked. But Clear's also work which is likely to be a better choice.
