Sometimes the fix has been done but the effect takes a while. For a cache to age out or a change to propogate. It all depends on what you are working with/on. Or you made a change but forgot to restart a specific service.

Meanwhile even though you did a fix correctly and aren’t aware of it, since it doesn’t seem to work you change something else and break it again inadvertently.

At first I was going to say there is ATI. Then I realized I hadn’t heard about ATI in a while and looked up what happened to it. Then I realized… I’m old.

For some reason the SMB2 theme song is stuck in my head all the time. Something about the jazziness of it.

If it is caching you can always set a ttl to a lower value like 5 seconds. And systems should be clearing the dns cache on a new ifup.

Set up an internal dns server that will resolve your specific host name to an internal ip and forward everything else.

If you just want a specific site, you can use bind and response policy zones. The advantage of this is that you can now configure your dns server to take advantage of block lists on the internet and block malware/ads/tracking domains.

/usr/lib or /usr/lib64 or /lib (some distros) or /lib64

Some things (like hosts file) are in /etc. /etc mostly contains configs.

The disk itself is flexible, hence the floppy disk. In contrast a hard disk had rigid platters, hence hard. The outer casing has nothing to do with it.
