Eircom DNS Oddness

rsynnott

For the last two days, my Eircom DSL has been taking roughly four seconds to resolve names. I thought this might be a router issue, but the effect is the same using the dns servers directly. Anyone seeing something similar?

I've been seeing it dropping pages every couple of times alright since maybe Thursday, but paid no real attention to it. Bit more of a pain today alright since I'm trying to work

It happens a lot to me, and seems to last for a few minutes, and then resolve (!!) itself. I've tried to get some support from Eircom on the matter, but it's impossibe to get past the front-line support monkeys and actually talk to someone knowledgeable about it. It was so bad at one time last year that I even installed a local DNS cacheing program.

You could use bt's dns as a secondary in your modem settings. Im with BT and I use Eircom's Dns as primary because they're updated more often than BT's. I have problems with them sometimes as described in above posts but I have BT's dns as a secondary so I bypass the problem.

Goodness, do they allow that? I would have thought they'd use some form of ACL.

Yep same here, does anyone know bt's settings?

IIRC:
194.125.2.240 - primary
194.125.2.241 - secondary

Thanks god! I thought it was just me. It was fine Thursday night, but then Friday morning it was aweful. I wonder did it have anything to do with the upgrade to the 4 exchanges that happened on Thursday night? I'm on the Finglas exchange and I know they were doing work on it on Friday morning between 1-5am.

DNS is taking ages for me too. Probably just the upgrading.

Most Irish ISP's DNS servers are open to all in my experience. Try a few others to see which give you the best performance.

(I don't even remember whose DNS IPs it is that I have memorized any more, I've been using them that long over various ISPs...)

Edit: ah, a quick nslookup tells me it's Netsource's.

Having the very same problem here on eircom. It's getting pretty annoying having to hit the refresh button 3 or 4 times before the page displays.

Ok just off the phone with eircom support. The guy I was talking to said there are no reported faults anywhere.

He got me to change my DNS settings however and it's much better now. Here's what he got me to do:

Go to your broadband connection in Network Connections. Right click on it and click properties. Select Internet Protocol (TCP/IP) and click properties. Select the last option 'Use the following DNS server addresses'. Enter:

Preferred: 159.134.237.6
Alternate: 159.134.248.17

Click OK and Close. That should do it. Mine is a lot better now.

Edit: Oh and he also got me to do a DNS flush. Start->Run - type cmd, press enter. Type ipconfig /flushdns, press enter.

Sorry to butt in guys but could my issue over on this thread be linked?

That's weird ... those are the old DNS server settings you always used to get before they changed over to the new ones (213.94.190.194 and 213.94.190.236), which is what my router is picking up automatically at the moment.

Yeah, the broadband support pages also give the 213.94..... DNS servers as the ones to use. The old ones are working great for me at the moment. Try them and report back.

Mine's working OK at the moment, but if I have any more trouble I'll try the old ones. Maybe they're under less strain now that DHCP's handing out the new addresses.

Mine's crap!

Popped the old ones in and everything nice and zippy now! thanks!

Was having the same issue for last couple of days, setting the DNS manually in my router (Eircom primary, esat secondary) sorted it out.

HSo

The last few weekend have been bad from friday evening until about noon on the saturday. DNS not responding. Rinning Eircom no help as all they ask is "have you antivirus." Perhaps its the upgrade. However before when my DNS was a limerick server there were no such problems. Now it looks as though the whole country is hooked into dublin DNS, could this be the problem?

excellent Waaaaaaaaaaaaay better cheers

deecom

Yeah old ones are the best!! (They just dont make those dns like they used to!!):D

Bit worrying that the eircom support site is down now too!

Shanegggg

Yeah same here, illustrates of how effective a quick goosey on boards can be
