DNS Strangeness Followup

A few days ago I mentioned I was having some DNS issues. I’m pretty sure they are resolved as the last few days I haven’t seen anything odd.
It seems the primary nameserver did not bump the SOA when it updated. As a result one of the other DNS servers was out of sync. [...]

DNS Strangeness

There’s some DNS funny business going on with this blog the past several days. I’m still trying to figure out exactly where the problem is. DNS has always been one of my least favorite things to deal with.

Me.com DNS Queries

I decided to take another look at me.com, the eve before we all expect a launch at WWDC2008. It’s still using marksmonitor.com for DNS.
TTL
The TTL is still set to 28800 (8 hours). I think this will drop before 2:00 AM PST (5:00 AM EST) if they are planning to offer email service to [...]

Phone 2.0: DNS Dialing Anyone?

I’m going to make a giant proposal to the web. Identifiers suck. Email, IM, Phone, etc. Most people have more than one of each. Lets fix that. Step by step.

Anycast Saves The Web

Several weeks ago the root servers were attacked. CNet is running a story that says Anycast played a role in preventing larger problems.
It would be interesting to see if all the root servers switch to Anycast. Where would the new distributed servers go? Does Verisign etc. own that many data centers? [...]

Root Server Attack

The root servers were attacked this morning. My guess would be few (if any) really felt the effects. This just goes to show that the net, despite being a distributed mess of networks still has a few critical points in its infrastructure. They didn’t take them down, and didn’t even get them [...]

Private DNS Address Space

RFC 1918 defines the following IP blocks as designated for private intranets:

10.0.0.0 - 10.255.255.255 (10/8 prefix)
172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

I think it’s about time we have the [...]

Google Outage

Seems google.com is down. Who turned off the lights? I wonder what happened? Did Googlefox cause a power surge?
Update #1 [7:13 PM EST]: It’s DNS related as this still works.
Update #2 [7:15 PM EST]: Seems to be coming back now.
Update #3 [7:39 PM EST]: Engadget suggests a DNS Hack, perhaps poisoning, but [...]

Well, domains are popular again

Domain-name registration surges according to a CNET news article.
How much is legitimate, and how many are just blog/email spammers treating domains as disposable?
