Pinging
I'm confused by pinging. I just moved hosts and have been pinging to see when my DNS propogated. It looks like it did switch over now because when I type in one of my domains it reveals the new host's IP address, but some other things strike me as odd:
1. I often get "Request Timed Out" and 50%, 75%, or 100% loss, yet I don't have any trouble reaching my site via a browser. If I have 100% loss then how can I have no trouble loading my website?
2. Other times it says mydomainname.com [IP address], but then when the results return it gives a completely different IP address followed by "Destination unreachable". Why the mystery IP address and how can it be unreachable and still return 0% loss?
Here are some of my domains if you want to ping them:
mikesussman.com
pstvalumni.com
carolinasoftball.net
hampton-homes.net
shootingstorm.com

It probably means that the DNS servers have not been fully propagated. How long has it been since you transferred. Also you should be doing traceroutes and nslookups.
tracert domainname.com
nslookup domainname.com
They will give you much more detailed information.

http://visualroute.visualware.co.uk is a really useful tool for doing nslookups via the web. (plus there are loads of international mirrors as well).
Will give you a good idea about the propogation of your DNS.

It's been a few days now but when I posted, it was within 24 hours of pointing to the new IP. Looks okay now. I just thought it was wierd to have 100% loss but be able to load my page fine. Thanks everybody.

Ping is also not 100% reliable as some block ICMP (Ping) requests. Most hosts don't though.

The point of routers is to find an available route, if one route fails they will try another. The fact that ICMP echo requests may be blocked in a router may mean that a ping route fails where a request on port 80 (http) gets through.
