DNS speed calls, no big deal if you have Linux. Just utilize the Host file.

1 or 2 alphanumeric characters, ie; G for google. I have utilized this feature for many years with no problems. You can even use upper and lower case.
Also, no additional work is required by the already overburdened IT staff, if
you program your own PCs hosts file. No mods to your router are required.

The benefit of translations on your own PC, beside higher security is;
faster connection times than if one goes to a standard or third party service provider, as in effect your machine is actually outputting the URL directly,
without the need of any DNS lookups.

Setups are typically less than a minute if your good. Just do a search on the
name (whois) and get their numeric address. Type in the numbers instead of the URL in the host file with a one or two digit abbreviated alphanumeric leter that is pointing to that address and your done.

When I type G in my Mozilla browser for google.com, it automatically checks my hosts file for a match, then I am connected much faster than if I use DNS
the old way.

Please also consider that profilers for advertising companies would love to
peek at your surfing preferences, then sell the info they aggregate.

Unfortunately, third party DNS providers can fall into this catagory.

You’d want to wait a second or two every time you load a new website? What planet are you from? Dialup-topia? :-)
