    I don't get what you are saying...

    www.google.com is a DNS CNAME record, a record which does not point to an IP address, but to another name. Windows tracert (and ping) utilities report the IP and the name returned by the server. CNAME records are useful if you want to have multiple (sub)domains that all point to a single IP address. You can, for example, create DNS A record that points realserver.google.com to the actual IP(s) of the server(s) and a bunch of other domains that point to realserver.google.com. Now, if the IP of the server changes, you only need to update one record.

    Tracert and Linux traceroute also do reverse DNS lookup, they ask the server for a name for that IP address. This depends primarily on the ISP, without their assistance I cannot change my reverse lookup entry, for example. While multiple domain names can point to a single IP, the IP only points to one domain name.

    So, with google it's like this:

    www.google.com is a CNAME record that points to www.l.google.com
    www.l.google.com is a A record that points to 74.125.77.147, 74.125.77.104 and 74.125.77.99
    74.125.77.147 points to ew-in-f147.1e100.net
    74.125.77.104 pints to ew-in-f104.1e100.net

    1e100.net is probably the ISP of that server. It looks like the reverse record is made using the last octet of the IP, what does ew-in-f mean you woud have to ask that IPS.

    In any case, that's why tracert reports:
    Tracing route to www.l.google.com [74.125.77.104]
    over a maximum of 30 hops: ...

      11 80 ms 80 ms 79 ms ew-in-f104.1e100.net [74.125.77.104]

    The relevance is that if the medium stays intact longer then I do not need to worry about it. For example - vinyl or shellac records. You need to clean them before playing, keep them in suitable temperature, humidity etc. However, other than that, you do not need to do anything, until you want to play a record and it does not matter if the last time you played it was a week or 10 years ago. No need to buy disks, make backups etc. just put them somewhere not very dusty (or use protective sleeves), humid or hot.

    The same can be said about analog video tapes, but video tapes do not last as long as records (a 60 year old record still plays ok).

    The same with audio tapes and cassettes. I can find a 15 year old cassette somewhere in the attic or wherever and it will most likely play.

    DVDs and other recordable digital media (except magneto optical disks, but they are too expensive) cannot be stored like records. Even if you want to play the disk once every 10 years, you will still probably need to access it more frequently just to keep it readable.

    Books, records, audio tapes and video tapes do not need that kind of maintenance.

    And if you think that copying a bunch of DVDs is nothing, try copying 200 of them. If I did not start using LTO tape to archive digital video/audio I would have more than 500 DVD-Rs by now, which I would need to copy every few years. I hope LTO tape lasts longer than DVD0-R and I'll have to swap less tapes when I'll need to copy them to LTO7 or whatever.

    However, for the magnetic tape, I do not need to continuously copy it every few years.

    Yes, I know that my issues are not because all digital systems behave the same. However, a VCR is so much simpler. Also, if I built a dedicated PC to record video, I could buy a lot of blank tapes for that price, and with tapes I would not need to buy separate storage, that is, even a big hard drive fill up, so I would need somewhere to put the recordings (I would probably just use LTO2) to free some space. With VHS I just store the tape, so for the price of a dedicated PC for video recording I could buy a lot of blanks.

    I also have a camcorder that records digitally (to miniDV tapes). It works OK.

    The difference between the camcorder and a PC is that a camcorder is a purpose built device (like a VCR), it does its function better than a multipurpose device (like a PC), that is independent of what technology is used to record. I am sure that a DV VCR or a HDD video recorder would work just as well as my VHS VCR does, but DV tapes are expensive and I already stated my problem with factory made HDD video recorders (DRM).

    Keeping a PC running can sometimes be more difficult than with a VCR. Now, while my computers are quite stable, my main PC crashed when I was recording a TV show. I was recording with a VCR and just using the PC to watch the video (since I don't have a separate TV or a Composite/S-Video->VGA converter). If I set a timer, I have to keep the PC running until it finishes recording. If I set a timer a week from now and go somewhere, if the PC crashes while I am away, the recording will not be made. A VCR only needs power, I can connect it to a UPS (it also helps that the VCR uses much less power than a PC) if I really want the recording.

    There are more things to video than quality. Ease of use is one of them. Reliability is another.

    With digital you need backups, you also need to actively copy the information from old media to newer. A DVD can be damaged beyond repair much easier. Compared to that, I can just store the tape for a long time and it will work. If it gets badly eaten, I can cut out the bad parts and splice the tape, usually though it works just with some lines on the screen. If the tape gets stepped on, I can transfer it to another shell (and clean the tape).

    My tape collection is like my record collection - I do not need to do anything until I want to play a tape/record.

    In any case, I have a video capture card, SD, but it is enough for me. I actually had that card before I had a VCR, however, I always had some problems with the video recording using a PC, that's why I said that VCR is more reliable:
    1.Sometimes the recorded file was without audio.
    2.Sometimes the file was without video.
    3.Sometimes the recorded file was with video and audio, but had dropouts, as if someone cut out random portions of the recording.
    4.Sometimes the recording would not start because the PC though that it would be a great time to change to/from DST, an app that I used to watch TV before setting the timer did not close properly and the capture card was still in use or some other problem.

    All in all, I had a success rate of about 40%, where the recording would start as set, be with sound and video, without dropouts and other problems. Oh, and I could not do anything with the PC while it was set to record. So, I finally fed up and just bought a VCR. Now my success rate is ~99%, I can use my PC while the timer is set and/or the VCR is recording. I can also use my VCR to record how I play games, since my VGA has a tv-out connector.
    I still use my video capture card, but I now use it to copy from VHS to DVD for other people, but I consider a PC to be unusable in doing things, that if they fail, there is no second try (like recording TV or radio shows, I use my VCR to record both) or each attempt takes a long time (for example: copying records - I use a cassette or r2r deck for that).

    3.On the other hand, If I want to store the show, I can just store the tape, unlike with hard drive based video recorders.

    In any case, my cable company provides analog as well as DVB-C signals, I can record from analog or use a digital tuner, which can be programmed to turn on at the specified time. However, I rarely record more than one show per day, so I just leave the digital tuner on and program my VCR.
    I am using the digital tuner because I bought my current VCR from abroad and it does not support PAL D/K, so I don't get audio. I tried to add a converter, but while it gave the audio, it also caused some interference with video for some reason.

    My next VCR will be a pro model, without tuner, but with more functions and higher quality mechanical parts (also, all functions accessible from the front panel). I also read in the manuals of some of the models that they have a function to start recording immediately after getting a video signal, which would mean that I would just need to set the timer on the digital tuner to record a show.

    3a.The creator can access this universe, but is bound by its laws of physics, so he cannot be everywhere at one for example.

    5.The Christians may be right up until this point. But the god may have created out universe for entertainment and he wants to watch humans fighting and killing each other. He might even reward people after death based of how many they killed.
