hop of those help? Your best bet is to use RegEx to parse the strings to see if URLs come up.
Using RegEx to then find the base domain and then vocalize that.

Hope this helps You should check for word boundaries by using \b. So, your regex instantiation would look like
code :
new RegExp("\\b" + dynamicString + "\\b","g")
at iteration
at-iteration
.at.iteration

To fix this issue You can use the Regex class and provide a delegate that will be called once for each match. It needs to return the string to replace the matched text with.
You simply have to declare a variable holding your counter:
code :
string a = "**MustbeReplaced**asdgasfsff**MustbeReplaced**asdfafasfsa";
int replacementIndex = 0;
string b = Regex.Replace(a, "MustbeReplaced", match =>
{
    replacementIndex++;
    return $"Replaced{replacementIndex}";
});
**Replaced1**asdgasfsff**Replaced2**asdfafasfsa
string a = "**Mustbe?Replaced**asdgasfsff**Mustbe?Replaced**asdfafasfsa";
int replacementIndex = 0;
string b = Regex.Replace(a, Regex.Escape("Mustbe?Replaced"), match =>
{
    replacementIndex++;
    return $"Replaced{replacementIndex}";
});

it fixes the issue A '^[a-zA-Z0-9_]+$' pattern matches an entire string that only consists of word chars (letters, digits, _). You seem to want to remove all chars other than those you specify in the regex character class.
Thus, you need to make it a negated character class and remove anchors, ^ (start of string) and $ (end of string).
code :
.replace(new RegExp('[^A-Za-z0-9' + customPattern.replace(/[\]^\\-]/g, '\\$&') + ']+', 'g'), '')

seems to work fine This following script written considering SQL Server but you can apply the same logic for other databases with changed syntax-
Note: This will only work considering your target string is the last part of your source string and the new string is fixed 'str[10.8.6.5.4]'
code :
DECLARE @S VARCHAR(MAX) = '2.2.2.3[1.2.3] - 4.3.2.1 - t+ 3 - kb - str[8.6.5.4.3]'

SELECT LEFT (@S, CHARINDEX('str[', @S,0) - 1) + 'str[10.8.6.5.4]'
