I'm posting this for reference, since many local ISPs seem to have intermittent problems with their DNS servers.

A malfunctioning DNS server in your ISP means that you can't access the Internet via the Domain Name System...e.g. www.yahoo.com, but have connectivity through numeric IP addresses.

Another symptom is when you can access your favorite sites (e.g. www.philmug.ph), but not most of the other sites. This happens because your Mac still has the DNS data stored in your computer's DNS cache.

The Internet is still there, your ISP just misplaced its address book.

PLDT's website posted DNS **down much of the time**

203.172.11.21
203.172.11.25
203.172.11.26

PLDT's DNS as provided by the DHCP server to your modem/router when a request is made (e.g. going online)

203.172.17.201
203.84.191.216

Globe's DNS, reported to work with PLDT DSL subscribers, is at:

203.177.255.10
203.177.255.11

There is an updated list of Internet ROOT-DNS Servers here

Avoid using these servers to set up your single computer.

These are root servers--- where ISPs and backbone providers get their DNS information, and are used primarily to initialize cache information in DNS serves brought online.

If you're a network admin, use your judgement on whether or not to include these servers in your parent DNS list
