DNS Servers

Under todays problems, we are being advised to change the primary to 212. 159. 6. 9 - this leads me to ask what are the correct permanent primary & secondary DNS servers that we should use please?

On the left under My Account, click on connection settings -> connection details

In addition there is a 4th DNS server 212.159.6.10 which has recently been introduced.

There are 2 alternate DNS servers should those 4 be down:

212.159.11.150
212.159.13.150

All 6 are currently working fine.

All four servers are primary/secondry.

212.159.13.49 / 212.159.13.50
These are located in Telehouse East and are best suited to customers on the two Redback units.

212.159.6.9 / 212.159.6.10
These are located in Telehouse North and are best suited to customers on the Juniper ERX.

Customers that have a @plus.net ADSL login need only use 13.49 / 13.50 for the time being.

PlusNet hope to make changes, such that the best DNS servers are assigned to you during your connection initilisation.

Customers with a @plusdsl.net ADSL login, can tell between the two different Telehouse suites by performing a traceroute to a site like portal.plus.net. The first PlusNet hop (either Hop 1 or 2 depending on your equipment, possibly 3 or 4) will contain the string "PTH" for TeleHouse Easy, and "PTN" for telehouse North.

Or you just set everything to server assigned and let PlusNet allocate the correct ones. You then just reboot your PC and router if you have one to get the correct DNS servers assigned to you.

Thank you both. having done a traceroute which showed 'pth' I have restored my settings to 13.49 & 13.50 - hope this is correct?

They are currently the ones automatically assigned so they are fine.

Interestingly a further traceroute with the restore settings shows ptn on the first 2 hops then pth on the third?

Indeed.

PlusNets main transit links are located in Telehouse east. This means that your data is transfered betweent he two sites before going onto the internet.

It is only the first hop in PlusNet that we need be concerned with.
