    I've seen a list of various domains, from this forum, that our TiVos phone home to. Was wondering if anyone with a Pi-hole or other domain blocking utility has blocked some of these domains. Are any other domains missing from this list?

    h1.tivoservice.com
    i.tivo.com
    log.core.cloud.vewd.com
    mm1.tivoservice.com
    mm1.tivoservice.com.localdomain
    sls.tivoservice.com
    tivo-0.vo.llnwd.net

    I'm temporarily using a mobile hotspot for my place, so my solution right now is AdGuard DNS. I just downgraded to TE3 and I don't stream (apps), nor share (household), or view anything remotely.

    I use pi-hole with TE3 on all my TiVo devices. I haven't seen a need to block any TiVo domains. The stats displayed by pi-hole show that interaction with TiVo sites is pretty minimal.

    I think we're gonna have to wait to see if someone with TE4 who is getting ads runs pi-hole and is able to successfully block them without fouling their other necessary calls to the TiVo mothership. Will be a trial and error process.

    At this point I don't see any reason to restrict its activity. In the last 24 hours TiVo has had 124 DNS request. I'm (purely) guessing you could block vewd.com as from its description it appears to be OTT based.

    Run an Internet Connection diagnostic test. Then go to System Information. Hit: Clear-Clear-Enter-Enter-0. Select Logs. You can see all the IP addresses used just for that test. Last time I checked it was 10. Everything a TiVo does is in those logs but there is no documentation.

    Do not block h1/h2 or sls as you will not get guide data. i and mm1/2 are needed for using the app and the website as far as I can tell. There are a slew of other letters I have come across from time-to-time that seem to be general replacements for h1/h2, you could literally go through the alphabet and ping them and see which ones respond. For a while, I was using my Pi-hole to auto-forward all TiVO h1/h2/etc... traffic to a single IP address, but that did not resolve my issues of failure at the download step every 3-9 days (and then needing to tether to my phone to clear it out), so I stopped doing that.

    code.jquery.com
    fonts.googleapis.com
    fonts.gstatic.com
    unpkg.com
    
    # Tivo specific hostnames:

    d2w343a14iggwx.cloudfront.net
    dju59wgerb63o.cloudfront.net
    
    # sketchy / probably don't need:
    log.core.cloud.vewd.com
    pactsafe.io
    
    # netflixy stuff (could be used for tivo+ if the streams are hosted by them)
    api-global.netflix.com
    appboot.netflix.com
    codex.nflxext.com
    ichnaea.netflix.com
    nrdp.nccp.netflix.com
    occ-0-590-586.1.nflxso.net
    push.prod.netflix.com
    secure.netflix.com
    
    With the following blocked it doesn't load TiVo+ correctly

    Code:
    adgwy.tivo.com
    api-global.netflix.com
    api.darksky.net
    api.tivo.com
    appboot.netflix.com
    business.tivo.com

    pdk.sj.tivo.com
    pixel.tivo.com
    pki.tivo.com
    sj.tivo.com
    www.pactsafe.io
    
    I don't know the side effects of this list, yet, haven't run into any after several reboots. I also want to pinpoint which one it is.
