Simple. The technical people at Comcast are highly skilled intelligent people. They aren't senior level techs at one of the largest ISPs in the world by being idiots. The legal department on the other hand is staffed by money-sucking weasels (like all legal departments are) who are supporting stupidity in legislation without bothering to talk to their highly skilled technical people about whether this braindead legislation is even technically POSSIBLE to implement. The technical people no doubt KNOW that SOPA is impossible with DNSSEC. Hence they're encouraging everyone to move to DNSSEC as quickly as possible, so in the event that Congress screws up and passes this abortion of a bill at the behest of the large content providers and intellectual property bandits, they'll find out that it doesn't work on large portions of the Internet, thus pissing off their constituents even more, and causing a large shift in political goodwill towards their opponents.

Has anybody suggested asking the current political candidates their views on SOPA? If you live in the US, and your Congressperson is listed as a Co-sponsor of the bill, or listed as an opponent of the bill, have you contacted them to voice your opinion? Votes are all that matters to politicians. A few hundred calls/emails to their office telling them that this is a flawed bill, and it WILL result in your vote going to their opponent can quickly change their minds on what matters to them.

That's the current list of SOPA co-sponsors.

Which government agency is the worst to get information from?

http://www.gutenberg.org/ Pick up a wide variety of classic literature for free. Or visit your local public library and ask the librarians there to help you find the section which fits your interests. Historical non-fiction, sci-fi/fantasy, or technology/military based fiction are prevalent out there. You'd probably get more recommendations if you had said what genres you wanted to read. Things like Terry Pratchett, Tom Clancy, Dale Brown or biographies of famous people are usually my choices for reading on a trip. The one advantage of picking them up in dead-tree format is you can read them while you're sitting for an hour waiting to taxi, when MP3 players and iPad/Kindles aren't allowed to be on. The downside to that is they're heavier to carry around with you.

Document everything you can.
Backup configs, make sure you save them frequently when things are working.
Get a good network management/monitoring package which uses SNMP to monitor the equipment.
Take as many classes and training sessions as you can.
Purchase vendor support for equipment. Cisco TAC is invaluable when the excrement hits the oscillating device. When the network is down, and the boss comes into the server room to ask when it's back up, it's much more comforting to hear that the vendor is helping you investigate the issue than to hear you have no idea what the problem is or when it might be fixed.
Build a lab to test/learn new protocols/ways of doing things. Have a couple servers in there, as well as the same type or smaller versions within the same family. If you're running Cisco 3945 routers in production, a lab with 1720s running 10 year old code doesn't help you troubleshoot production issues or test code upgrades.
A good podcast which covers CCNA/CCNP level topics with examples:

How to backup your devices:

Netdisco, good tool for network discovery and host tracking

Join and read network mailing lists. NANOG, Cisco-NSP, Juniper-NSP are a good place to start. http://puck.nether.net/mailman/listinfo/ to subscribe to several of those.
Beyond that, good luck. Speaking as someone who has been doing systems/network administration for close to 15 years, you will learn something new every day. If you don't, you're not trying hard enough.

Show of hands, who else did a whois on those IPs and noticed they're registered to Microsoft in Ireland and Great Britain? I get enough crap from Microsoft, why would I want to let more in?

Which was end-of-lifed almost 3.5 years ago, so I wouldn't see why anybody would be putting in one of these systems anymore.
