[Business] Looking to downgrade internet

So I am trying to cut some monthly costs and just talked to a Comcast rep. Even though I have verified here with multiple sources, before I pulled the trigger, I wanted to verify with the rep that 5 dhcp addresses are possible once I remove my static ip block. His response was that you only get one.

I know NetFixer See Profile has confirmed the 5 available dhcp addresses in the past, but am looking for some additional reassurance before I do this. I will be dropping my static ip block and purchasing my own modem.

Here is a link to a recent post by NetDog See Profile regarding that subject: »Re: [IPv6] Customer Owned Devices with Business Services

TL;DR -- Five dynamic IPv4 addresses, and more dynamic IPv6 addresses than anyone could possibly use.

Any standard cable modem (or a bridged gateway) for which the customer is paying for a "c02" (two IP addresses), or a "c05" (five IP addresses) config file.

I have personally had no problems with Comcast's BCI config file allowing me to get up to five simultaneous dynamic IP addresses on a bridged SMCD3G-CCR, an SB6121, or a DOCSIS2 DCM-202.

Here is a log excerpt from my current SB6121 that shows the BCI "c05" config file that is being used:




Here is a current "Addresses" display from the SB6121 that I am currently using with three routers behind it:
