    The best security practice for wireless is to use the strongest encryption available which means upgrading hardware if needed. Currently for home use, WPA2 is the best encryption available. Also, the use of strong passphrases is the next best practice which mitigates dictionary/brute force attacks.

    Something else I forgot to mention on this topic of DHCP as a security risk. The reason why some people felt turning off DHCP is a security step is to slow down someone with unauthorized access who has "physical" access to your network. But there are ways today to mitigate unauthorized physical access such 802.1x.

    While this may be all well and good, the topic really is: mrv stopped working
    [and not DHCP]

    Some Very Good Points which is Why I Posed the Question.

    I need Enlightenment.

    Thanks, Guys for your Responses.

    Chances are pretty good that the router assigns addresses based on a hash of the MAC address. This brings a modicum of uniqueness while making repeatability likely.

    I worry about routers that give out seemingly random assignments with each renewal.

    The question was asked as to certain topics around DHCP to even include you per quoted below.

    So I don't know what your problem is as this isn't the first time you've interjected like this.

    And at what point does it wander beyond the topic, or the context of MRV?
    "For me" was after your forth post in a row without anyone replying to them.

    Well, back to the Topic.

    I highly recommend "Static" IP Addresses to avoid problems associated between the Router, the DVRs and MRV (WHDVR Service) as many of us in the past have concluded that this helps eliminate a lot of MRV Problems that we could not pinpoint as to why but they happened and were eliminated by the above Fix!!!

    You're free not to read them. And I'll certainly not repond to any of your questions now as you feel they're wandering.

    I was replying to specific posts either answering questions or clarifying points that were off shoots from the discussion of DHCP and security.

    Maybe no one is replying to my posts as maybe I've answered those specific questions and there's no need to discuss further.

    It seems that you have issues with people who can deep dive into specific topics further than what you can.

    My posts stand as they are and if you feel compelled to have the moderators close or delete my posts here...go right ahead.

    Having been "some what" :)lol:) involved with MRV, some routers handle it well, and some don't as well. For those that lose connection, going with static [and outside the DHCP range] has proven to work.

    You made some good posts, which wasn't the point, nor was anyone being able to go farther into a subject than myself.
    "The point", was more to get back to the thread topic, and not turn this in to who can "out network" the next poster.

    I understand your point and this will be the last thing I'll say to keep from de-railing the thread. Some of my posts in direct response to posts where a question wasn't answered but was an answer to question was to bring up what I feel as misinformation or a bit misleading. I post what I post to try to help people understand topics around networking and if I feel there are things that I see as inaccurate or not correct, I will point it out.

    If you want to continue this discussion or anyone else for that matter, can reach me via PM.

    Back to the topic.

    I never really understood why anyone would use reservations. For a mobile device maybe, but IMO it makes life a whole lot simpler just to use static IPs to begin with and never have to worry about DHCP.

    BINGO!!! We have a Winner!!! :hurah:

    P.S. For the answer to your question, those of us who have done it, didn't know better until later after we had done it. It was explained to me why TRUE "STATIC" IP ADDRESSES are much better and don't have to have their leases renegotiated ever.

    I can explain that one for you. Ease of (centralized) management.

    Let's say you have 100 VM's that are servers. Heck, for that matter it could be 100 print servers. You want to give them all a fixed address and make your life as easy as possible so you can still take 2 hour lunches.

    You could create an excel document with the hostnames and IP addresses an then configure all 100 of these end points with their network setttings and then hope that no one ever jacks it up. This will involve either walking over to the device, or writing some scripts to remotely configure them.

    Or you could create 100 reservations on your DHCP server and just leave those 100 devices alone.

    The 100 reservations are authoritative. The excel sheet? Well we hope the techs did it that way. And if you need to change an address you just update the reservation rather then update the excel and go reconfigure the device.

    For home use you are 100% correct, but in an environment with 100's or 1000's of devices, DHCP and reservations when necessary is critical to be able to manage things. Someone with a dozen or so IP devices, static addressing is fine...
