Broomall, PA | Educate me What can cause a DNS server to hic up?
And why can't Comcast just do a DHCP refresh to all subscribers so that they get functioning DNS server either like 4.2.2.1 etc when they know they have a long repair ahead of them? |
|
| It is because 4.2.2.2 is not a Comcast DNS server. They do not support it or even have access to it. There is issues with using someone else's DNS servers, they must use their own.

Broomall, PA | So why don't they have a backup DNS server on hot standby and they just take the active ones off and take their time to figure out how to fix for good?
I would think such a national ISP should have back ups.
Is my asking this to out of line? |
|
| They have a 2nd server farm, and apparently that is having issues as well. That is usually the "back up". Both are messed up right now at the moment. I do believe they should have other backups just in case, but pushing A DHCP request wouldnt work unless your lease expired that day at that moment, which is rare since we have 7 day DHCP leases.

| DSL or another provider I had Comcast for the longest time. Only because they where the only high speed Internet service in my area. Through out that whole time, my system was hacked into and their abuse department slept and replied with auto email only. Less then 5min after the tech had hooked me up, it had already started. Thus I had not even had the chance to even use my Internet before the problem began.
Their policy on any problem, unless 1,000 or more people call up and report it is... "It's your fault." Even if they admit to themselves that they have a problem, it has to be your fault. So many people who reported the DNS problems got that reply before it got out of hand.
Also they like to double bill you. Do you own your own modem? You do? Prove it! On DSLreports.com we have users who where told to prove they own their own modems, who where getting billed for renting them. Others who where being billed for cable boxes they never had.
60.95 if you do not use any of their other services, but 15.00 off if you do. Either way, they'll get the money and that is all they really care about.
With Verizon it's only 29.95 for the same speed 3MB download, but you get a higher upload speed of 756kb. Comcast still uses 256kb max. Although I personally do not worry about my home upload speed.
My advice... Go with another provider if you can. I was lucky enough to have finally been able to sign up with Verizon. It took a while to get it at my address, but it's here & I'm not looking back.

Re: Educate me You know I would think that DHCP, DNS, Email, Newsgroup those kind of services that been around for a while for any ISP would be the last to go wrong just because I thought that knowledge in those things would be rock solid and just work because they have them down pat. I guess I am wrong or the ISP has some new IT people just learning the ropes. |

Re: DSL or another provider Yes, Comcast has it's problems, but it must say something if I'm back with them after having SBC at 3008/512 for $29.95, the problem is at least Comcast's tech support is English speaking, while SBC's tends to be non-native English speaking personnel. And Comcast's max upload is now longer (at least in most areas) 256 Kb/s, it is now 384 Kb/s. |

Re: Educate me The main problem is that the DNS servers seem to stop responding. Previously Comcast had multiple DNS servers throughout the country. They thought it would be a good idea to consolidate all these servers into a handful (probably to save money). Unfortunately this is what happens when you put all your eggs in one basket.

Re: DSL or another provider I wouldn't go with Verizon unless it was a deal with Fios. Noway would I go back to having telco service from them. Comcast by and far been reliable for me locally because we got good techs in our area I think and the one is very responsive in the boards sometimes. I kind like learning about this technology and its problems and I wouldn't mind learning what is causing the DNS issue. |

I don't use comcast's crappy dns servers, we have way to many hackers on the philly dns network and are abusing the dns servers here. I just use 4.2.2.1-4.2.2.6 level3 is much better than crappy comcast's dns servers. I have very little problems with comcast but if I do I just post here on bbr. Comcast's support is 3thrd party therefor they know nothing except for what's in front of them on the computer screen. |

How often does 4.2.2.1-4.2.2.6 level 3 servers change/refresh ip addresses.
I like my IP static so i can do stuff on my server when i'm not at home (plus dont want to do the dynamic dns thingy). |

Given the critical nature of DNS servers, it's rather rare that their IPs ever change.

I guess I am wrong or the ISP has some new IT people just learning the ropes. You'd be wrong. Core services such as Email, DNS and Newsgroups are all fairly esoteric skill sets. They become particularly challenging when you run any of them with any level of scale and/or complexity.
Never confuse the apparent ease of doing things on your home network (or even a small office) with what it takes to provide a service to thousands or millions of users.

You sure they actually cut down on the number of name servers and didn't simply put them all behind a geographic redirector type of network appliance?

Re: DSL or another provider Are you saying that say my current ip from comcast is a.b.c.d, and i change my routers WAN setting to use static instead of DHCP with DNS 4.2.2.1-4.2.2.6 level 3 servers, my IP address will remain as a.b.c.d
hope this aint a stupid ques... |

Alexandria, VA | Your DNS servers' IPs have no effect on yours (and vice versa). The only time the one or the other counts is if there are access controls in place.

@strl1201.mi.comcast. | OK... this is the situation,
i get a dynamic IP from comcast, if i use static values for my router and comcast refreshes their DHCP i might run into problems right???
OR if i change my DNS servers to the level 3 ones is this where i will be assigned my IP from???
I'm confused. I dont want to use comcast DNS as it is unreliable, and at the same time i dont want my IP to change just like that. |

Re: Educate me Set your DNS servers to your choice (4.2.2.2 / 4.2.2.3). DHCP will assign your IP and have no affect on your DNS servers. As Kilted Freak said...

I don't believe they did since every Comcast user now has the same ip addresses for the primary and secondary DNS servers. If it was using a redirection the ip addresses would change depending on the location.
