I am asking this here since Comcast Reps will not advise on device configuration for Static IPs., so I am hoping someone can shed some light on this. I have a BWG modem (being replaced soon) and a block of 5 Static IPs, x.x.x.25 – x.x.x.29, with a "gateway IP" of x.x.x.30. Now, if I manually c

For the first time, I logged into my Comcast Business account, went to the "Manage Services", "Internet", page, and noticed a link to "View Static IP", so I clicked on it.It brings up a page that not only shows the static IPv4 addresses I know very well, but also "Static IPv6 Information", which is

I have a /56 static on Comcast Business. Recently I had a cable modem issue (as determiend by comcast) and the cable modem was replaced.  Everything is working, but I received a different /59  (still inside my /56) so I had to renumber several vlans!  How do I keep this from changing

I’ve run into a blocker switching from Business to Residential. After calling business support, all I need to do is activate residential service through Xfinity, then sign the voluntary disconnect form they sent me to turn off business service. My address is blocked for use on Xfinity. It says “thi

Business Class customers have contacted us asking, “What are Comcast’s name servers?  I need to know so I can use my own domain for Comcast services.”

When Comcast credited my payment to the wrong account last May, my subsequent payments were always one month late, but still early enough not to incur a late fee. As such, I was not aware of the misplaced payment until I was charged with a late payment fee several months later. That led me to resear

I have a SMC SMCD3G-CCR with five static IP's, routing/firewalling is handled by an external device (the SMC doesn't have the memory/grunt to deal with my stack).Recently, the SMC has started randomly 'hanging'.

I've been trying to pin down the cause of some machines having slow internet upload speed and I seem to have tracked it down to static IPs. Machines that get NAT addresses straight from the modem have good upload speed but everything that is assigned a static IP, either routers or individual machine

I am unable to sign into my comcast gateway with the default username and password. Could I get the password reset please? Thanks!

In 2020 I contracted with Comcast for a package called Business Internet 500, and I have been able to use my own modem (a Netgear CM1000) for Internet service (no other services). As the contract was nearing expiration, I called and spoke with a sales representative. He told me that Comcast Business

I am beyond livid at this point. The constant run around the constant it's not us it's you or never following up is getting really old.  Last visit was several months ago for another outage and they couldn't find the node we are on and was supposed to get back to us.  NO WORD & that w

I used to go to Advanced Settings under Business Voice User to change BLF settings, but that option no longer appears there, and I can't find it. Is this a temporary portal issue, or has its location changed?

I host my own name servers and have a new /28 block and /56 block ipv4/6 from comcast and I would like to be able to manage my own PTR records (e.g.: [rfc2317](https://www.rfc-editor.org/rfc/rfc2317)) for my static ipv4 and ipv6 blocks.  If not, here is the list of ip addresses and their names

I recently upgraded my service and I have this new CBR-T wireless router.  When first installed I did not have time to reset all my rules from my old router so I called support to get a manual on the modem.  They asked what I needed and they switched the modem to passthrough mode. I now want to use
