[ale] Comcast DNS

[James Taylor]

I'm not sure what you are trying to accomplish.
It looks like the first two DNS intries are the same as what you were using before,
You shouldn't  even need to reference the secondary DNS unless the primary is down, and the tertiary only if both the primary and secondary servers don't respond. 
 
It's possible that, if you are still point to the old DNS servers, that they are somehow blocked and timing out until you hit the tertiary, and you are getting delays because of this.

Can you telnet to all of the servers on port 53?

Since moving from Charter to Comcast I've noticed that connecting to 
sites have drastically slowed down. My DNS config used to be:
Primary DNS: 64.94.1.1
Secondary DNS: 64.94.1.33
Tertiary DNS: (I don't remember for Charter)
DNS search path: nothing specified

Now my config is:

Primary DNS: 64.94.1.1
Secondary DNS: 64.94.1.33
Tertiary DNS: 68.87.68.162
DNS search path: hsd1.ga.comcast.net

When I do a nslookup of DNS 1 & DNS 3 I get:
[scott at ncc1701f ~]$ nslookup 64.94.1.1
Server:        64.94.1.1
Address:    64.94.1.1#53

Non-authoritative answer:
1.1.94.64.in-addr.arpa    name = ns1.acs.pnap.net.

Authoritative answers can be found from:
1.94.64.in-addr.arpa    nameserver = ns-c.pnap.net.
1.94.64.in-addr.arpa    nameserver = ns-d.pnap.net.
1.94.64.in-addr.arpa    nameserver = ns-a.pnap.net.
1.94.64.in-addr.arpa    nameserver = ns-b.pnap.net.
ns-a.pnap.net    internet address = 64.94.123.4
ns-b.pnap.net    internet address = 64.94.123.36
ns-c.pnap.net    internet address = 64.95.61.4
ns-d.pnap.net    internet address = 64.95.61.36

[scott at ncc1701f ~]$ nslookup 68.87.68.162
Server:        64.94.1.1
Address:    64.94.1.1#53

Non-authoritative answer:
162.68.87.68.in-addr.arpa    name = cns.s3woodstock.ga.atlanta.comcast.net.

Authoritative answers can be found from:
87.68.in-addr.arpa    nameserver = DNS103.comcast.net.
87.68.in-addr.arpa    nameserver = DNS101.comcast.net.
87.68.in-addr.arpa    nameserver = DNS102.comcast.net.

Any suggestions as to what I should use? And how would I manually set 
it, as I'm using DHCP form my Linksys router that only has places for 
DNS 1 & 2.

TIA
Scott
