As we're now pretty much stuck with ipv6, they would be better off locking out all the later bits until the transition is complete and make the ipv4 directly translatable. I.e. 192.168.25.25 becomes just FFFF:C0A8:1919 and all other ipv6 numbers are off limits until the transition is complete.
ARIN rules for acquiring IP addresses still apply to traded blocks, and those rules keep anyone from hording. ARIN has to authorize all transactions and even has something like an $8 fee for each IP traded.
Several weeks. Sounds like a goof trade off. Cause massive disruption and waste thousands of man-hours of time just so the rest of the world can gain a brief instant of time.
I've ran into situations where not using GOTO resulted in much messier code that was harder to read. This rarely happens, but it does happen, and I always take a step back and try to find a better way than using GOTO.
It does increase efficiency for certain types of common work a lot. Doing more work in the same amount of time is the same as doing the same amount of work in less time, with oblivious scaling limitations for different bottlenecks.
I have a CyberPower surge protector with a built in 1Gb protector, but when I use it, I sporadically get lots of frame errors for tens of seconds, like in the 1-5% range.
Surge protection for Ethernet costs more per port than nearly any switch. Not sure why it's so expensive. Cheaper to just have proper power surge protection.
What you say is true, but only if one of the devices is already compromised. Chicken and Egg issue. In order to compromise a device by accessing its admin interface, you first need a compromised device that allows you to jump VLANs. Of course a VLAN ID miss-match or a miss-configured switch could allow a network device to forge packets that hop VLANs, assuming the switch has such a security issue, which has happened. Security is done in layers. Don't assume any layer is impervious.
There will be much less of a difference soon(tm). With the changes coming to FreeBSD and PFSense, you'll be able to easily build a firewall+router for under $1500 that can do 40Gb/s full-duplex line-late 64byte packet stateful firewalling, NATing, and routing. Once they get the basic platform out, their next goal is to further optimize it and are expecting near 100Gb rates. Of course if you disable the stateful firewall and NAT, you'll be able to handle much more traffic.
The discussion was about routers not protected by firewalls. Most home "routers" are firewalls. that being said, my above post is how I have my home network setup.
You don't have your router's admin interface limited to the admin VLAN, locked down to SSH with keys, and restricted the admin VLAN to VPN access or devices with no internet access?
Lag is caused by bufferbloat. A simple AQM can make a 512kbit connection have low latency when attempting to download or stream. On the opposite side of the spectrum, I've seen 100Mb cable connection have 1000ms+ pings when attempting to stream or download because of bufferbloat. My ISP seems to use an AQM. Even when downloading from torrent and full speed, my jitter stays under 5ms. I've run DDOS tests against my home connection, sending 120Mb/s to my 100Mb link, and I was getting about 20% packetloss, but my ping was only about 20ms over idle. Always a low ping.
I can get a guaranteed 20/20 for $20/m, 70/70 for $35/m, and 100/100 for $45/m. My first hop is the same as enterprise connections. I am one hop from their core router, and when I trace routed from work on their enterprise 10Gb link, the first hop was exactly the same. The only different is the Layer 2. I am connection via non-oversubscribed GPON and my work is connected via 10Gb active Ethernet. I still have dedicated bandwidth. 2.5Gb down and 1.24Gb up among 32 customers, but my ISP will not over-provision, and regularly rebalanace GPON ports anytime someone changes speeds such that they'd over-subscribe the port. "100% of our customer could use 100% of their provisioned bandwidth to the trunk."
Surely the must skimp somewhere? Nope, Level 3 is the upstream for all traffic, no shitty peering, everything is Level 3. Technically $45 for 100/100 gets you a business connection, just not an enterprise connection. No SLA, but most businesses do just fine with their after-midnight maintenance. I asked them about the trunk and enterprise connections. They do no prioritize them at all. They do not use QoS for any customer traffic in any way, only internal diagnostic and administration traffic.
How expensive is 50Mb? Not very, at least not for home users. Less than $35/m I'd wager. I should mention that my ISP has turned down all government grants and loans. They're a small town ISP doing this all on their own dime.
the triple-pane windows are getting popular here in the US
That's pretty sad. I live in the USA and the house I lived in 20 years ago as a child had triple pane windows. Of course the 4,000 sq-ft house has a lower electric and gas bill than my small apartment. Who need insulation when you can let someone else cover the energy bill?
What's wrong with the roads that you lose control when they're wet? Up north, you can slam on your breaks and maintain decent traction is very deep water and high speeds.
Experience doesn't count for jack. It's hard to tell how good a person will be until they've worked there for a bit. Resumes are mostly white lies. Nearly everyone we interview has a great resume, but nearly everyone we interview seems to be a fake. Ohh yes, offer more money. Holy crap. Even more people with awesome resumes come out of the wood work. You were a DBA for 5 years, but can't hold a conversation about indexes? Been programming.Net/Java for 5 years, don't understand the garbage collector? Been writing Web Apps for 5 years, don't know the basic theory behind asynchronous programs? Bah.
"The only real reason I got into this was you were so good at it. You were my inspiration..."
I got into programming because when I first saw a computer when I was 6, I thought, "I could make those do anything I can think of". I didn't need "inspiration", a role model, or any of that crap. All I saw was a screen saver running and realized it was programmatically generating images. I tried Basic, hated it. Jumped into C and ASM.
I've never understood how people don't know what they want to do. Do you enjoy this food? Do you like this picture? Come on! Do people know anything about themselves?
Look for a company that cares about quality and you'll find quality workers. There are as many crappy companies as there are crappy programmers. It can take a bit of effort for a good programmer to find a good company.

They did do this, it's a standard already. Not to mention dual-stack. http://www.tcpipguide.com/free...
Had to remember to mess with ip6tables to default deny on inbound
Don't you have a stateful firewall that blocks all incoming traffic by default?

But some fool was stupid enough to take the contract and not be able to deliver.

Great point, but to drive it home further, Cisco and Huawei both have core routers with petabit label routing.

I can get a 20/20 dedicated connection for $20+sale-tax, no hidden fees, no cap, no installation cost, transit provider is Level 3. Midwest USA!
