Most of our customers just do management over the public network. There was one that had a PVC for management; I’m not sure why they did. Since CPEs do SSL, the thought is that it’s good enough.

Subject: Re:

We are going to use a separate management WAN, in private IP space, but one group of people want to do DNS names, while the other group wants IP. So I thought I would poll and see how others are doing it. Because of technical reasons, we have to use the IP - modems don't do dual DNS stacks and we don't want to resolve all DNS on the management interface.

As for DHCP option, I found a better way of doing this yesterday:
# Define a custom option space for tr069 options
option space tr069;
option tr069.acs-server-url code 1 = text;
vendor-option-space tr069;
option tr069.acs-server-url “http://url/of/acs/server”<http://url/of/acs/server%E2%80%9D>;

On the few modems we've tried, this works perfectly. And this value overrides the ACS URL that is preconfigured into the CPE.

I'd recommend using a separate WAN connection for management when
possible. As for using a domain name vs an IP, I prefer using IP because
then you deal with one less point of failure (i.e. DNS). Though I don't
have a strong opinion about that.

I personally haven't used the DHCP option because I try to minimize the
number of client features I have to rely on for a smoother operation.
Perhaps my opinion will change when TR-069 is more wide spread and
client implementations improve.
