As assumed, this did not work.
But I found, where the problem might be located...
With a smalle testfile I tried this after
running my script:
===============================================
> levels(selected$host)
[1] "22.99.44.101" "266.249.71.143" "5.66.61.230" "66.29.1.13"
[5] "7.6.1.20" "7.6.14.240"

[1] "7.6.1.20" "7.6.14.240" "5.66.61.230"

So, somehow there are unused levels inside.
Using drop=TRUE in split() did not helped.
So I have somewhere later to fix it.
But when I do it before tapply, there will be an error-message...
Ciao,
