I'm getting very close to having everything I need to get my pfsense install all ready to go and in reading some tutorials for that I've come across a few suggestions to use OpenDNS, is anyone here using it? What are some of the benefits that using it brings you? Please don't link me to their page, I've been doing some reading over there too.
 
There is many Urban Myths about OpenDNS, so YMMV.

The most known Myth is Surfing Speed increase, which is Not True in 98% of the time.

However if you want to use the OpenDNS Proxy like services concerning Blocking and controling what is available to the surfers on your network it is a very good tool.

As for the speed, depends on how fast your ISP DNS is. InsightBB's was pretty bad at one time and OpenDNS beat the pants off of it. Since then, I've moved to Level 3 (4.2.2.1, 4.2.2.2, 4.2.2.3,etc) or ATT DNS. Ping around 16-20ms to either of those with fast lookups. Can tell vs ISP DNS.

Interesting, I had always thought that the 4.0.0.0/8 Class A was owned by Verizon... IP Whois proves you to be correct though.
 
I use it at home to restrict my kids access to certain things. My ISP definitely does not give me the ability to block dns lookups for porn/drugs/crap like opendns does. On my router (PFSense) I use dns-o-matic to update both opendns and dyndns and block access to any other dns server via the firewall. Works great and is very low maintenance. I believe this is what Netgear is trying to accomplish with there recent partnership.
 
I switched to it a couple weeks ago. I do notice a speed increase. I mostly did it for the secondary benefits:
- Blocks known attack sites
- Rewrites commonly mistyped URLs
 
I switched my sister's computers over to it when I noticed her laptop sticking on "looking up www...". OpenDNS was much faster than her ISPs lookups.
 
I use it for the content filtering. I'm working on getting a linux box setup running Dan's Guardian, once that's in place I may switch back to my ISP's DNS.
