This one with matching 4 numbers separated by dots is better, one can
add restrictions that the last two numbers are in the range 0-255, if
one wants to be more strict, but the expression will get more complex.
However, it is recommended to use ^ and $ to enclose the expression and
do not match hostnames like my10.10.10.10domain.com.
The first example in this discussion $rd =~ "10\.10\..+" can match also
other ips not in wanted range, like 8.10.10.23
As for matching the . (dot), it has to be escaped like \., however over
the time working with different libraries, scripting languages and
parameters evaluation (which may require \\.) I developed the habit of
using [ ] for matching the special characters, like here it would be $rd
=~ "^10[.]10[.].+".
Just to follow on Alex' remark.
Otherwise, the match with ipops function is the most accurate for this case.
To complete for those that are not aware of, one can avoid regex
matching if wanted to match on prefix: starts_with("$rd", "10.10.").
Then fnmatch() function can be also useful in some cases, it does
shell-like pattern matching for file names.
Cheers,
Daniel

I would try:
if(uri=~"10\.10\.10\.[[:digit:]]+\.[[:digit:]]+")
or
if(uri=~"10\.10\.10\.[0-9]+\.[0-9]+")
