| Re: Keep in mind... said by tubbynet  :comcast wants to display the outward projection that they are faster/better/more reliable than opendns. as a result, people may be more likely to stay with comcast dns servers/switch from 3rd party dns back to comcast. combine the influx with a lack of understanding about dns redirection and you have a new cash flow. The Comcast DNS servers are more likely to have better returns for sites that used DNS-based global load balancing like Akamai, Google, Amazon, Yahoo, Limelight (Netflix streaming), etc.
There are a number of ISPs doing DNS redirection now, but I still give Comcast the nod for offering up an entire set of DNS servers that are redirection-free. »dns.comcast.net/dns-ip-addresses2.php
Sure, that doesn't help people who simply take their IP's DNS servers as assigned by DHCP, but I'd argue the majority of those folks are the group of users least affected by DNS redirection. | |

1 edit | Re: Keep in mind... said by espaeth :The Comcast DNS servers are more likely to have better returns for sites that used DNS-based global load balancing like Akamai, Google, Amazon, Yahoo, Limelight (Netflix streaming), etc. on this, i almost have no doubt. i attribute a lot of cdn speed/transfer issues to improper dns glb*. i'm not saying there aren't benefits.
however, in the wake of the dns-poisoning scare several months back, how many people blindly switched to opendns because other people said it was "better"? if comcast can put out enough pr that says that they are better than opendns (and can provide the modicum of proof required to convince the average internet user), those users may switch again to using comcast hosted dns (more than likely by accepting the dns servers from dhcp). as such, you have a new group of converts that will be affected by your dns redirection.
is it a step in the right direction? sure. comcast is being open and transparent about a lot of their network changes. however, i'm tempted to believe that they see an additional income value in doing this as well.
q
*[edit] i realize that my wording of improper dns glb is partially incorrect. i am leaving the current wording with the caveat that it is improper due to the poor result return from the query from dns, not due to an improper design in the overal dns glb.

Since when was a cable giant (or any large telco company) ever interested in "helping out" other companies? We're happy to support ISC, which is a non-profit company that does a lot of great things for the Internet community. See their website for details on their mission at »https://www.isc.org/.
But apart from that, we have a very large ISP business and many of our services are built using IP technologies. As a result, this brings with it what I view as certain responsibilities (in my personal opinion) to support the continued good health and growth of the Internet organizations and foundations so critical to the Internet.
That includes things like being major sponsors of the IETF, ISOC, NANOG, MAAWG, and many, many more. Sometimes these organizations are simply generally focused on seeing that the Internet continues to thrive, while in other cases they may be more narrowly focused on security, stable network operations, DNS security, IPv6, or other topics. We may not talk about it very much, but we are big supporters of the many key organizations that make up critical parts of the Internet community.

Your personal opinion is good and all, but Comcast is a corporation and thus is amoral. They would never spend money on ANYTHING unless they could profit from it. All the day traders shareholders would be screaming bloody murder otherwise.
No, one way or another Comcast will try to profit from this.

Amorality is generally a poor long term business strategy. Shareholders tend to scream bloody murder when a company they're invested in performs amoral acts.
Some people tend to confuse "They don't conform their business around my whims" with corporate amorality. But conforming to the delusional narcissism of individual customers is an even worse business plan then amorality. | |

Actually, all they need to do is put a spin on it and show a slightly larger quarterly profit and the shareholders won't care. Have you seen the economy recently? No one cares about the long term, everything's 'what can we do to make a crapload of money next quarter' or 'how can we inflate our stock prices even more.'
Anyway, this was not "we can implement our new initiative by doing this and make $x but piss off a lot of people, or we can do that and only make $y but everyone will love us." No, you're saying a public company instead said "we're going to spend $z to make $0 while hoping maybe 0.1% of our customers will even notice?" I think not. No, they're doing this to gain something, not because they want to be 'nice.'

Very interesting move on Comcast's part I would have to say. I may just be paranoid, but I think there is something more to this than meets the eye. I'm keeping my tin foil hat on for that one.
What would be even MORE interesting is if Comcast launches a "cache lookup" like what OpenDNS has and give people the ability to refresh Comcast's DNS cache. If that happens, then perhaps Comcast isn't some evil corporation bent on making as much cash as it possibly can.
Though to play devil's advocate - I think Comcast is trying its hardest to show that it does follow network neutral rules and plays nice with everyone else in the sandbox. Once the network neutrality stuff hits the fan, I bet Comcast is stacking its cards so that they can just whistle and laugh at other ISPs, while AT&T and other ISPs are crying themselves to sleep.
My two cents. | |

I meant something similar to OpenDNS's cache update. Basically you type in a domain, and it tells you what their servers are reporting and you have the ability to "refresh" the cache for that one domain. | |

That's the impression I get too. And I think that Comcast is getting way too big. They need to be cut down to size. There no where near the size of Verizon, or ATT. They needs to be a lift on the 30% rule on cable. I think Comcast and Cablevision should do business level data.

By hosting their own DNS Root Server, what are they saving in time..2-7 ms, if that? There are 36+ root servers in the US.. I guess another root server wouldn't hurt.. I guess Comcast will get to have "M" or would it fall under the ISC umbrella? (edit:nevermind, the answer is in the opening paragraph)

| Should be a good thing for everyone. Unless I am missing something, this should be a good thing for everyone. For Comcast users their results should be faster as they have a "on network" root server. For the rest of us this should help us, as the "normal" root server load that Comcast users previously generated is no longer there, freeing up server time for the rest of us. | |
