    Try this simple way checking range

    DECLARE @IP NVARCHAR(30)='192.168.500.1'
    
    SELECT  * FROM 
    Branches
    WHERE
    CAST (PARSENAME(@IP,4) AS INT)>=CAST(PARSENAME(IPLow,4) AS INT) AND CAST(PARSENAME(@IP,3) AS INT)>=CAST(PARSENAME(IPLow,3) AS INT) AND CAST(PARSENAME(@IP,2) AS INT)>=CAST(PARSENAME(IPLow,2) AS INT) AND CAST(PARSENAME(@IP,1) AS INT)>=CAST(PARSENAME(IPLow,1) AS INT)
    AND
    CAST(PARSENAME( @IP,4) AS INT) <= CAST(PARSENAME(IPHigh ,4) AS INT) AND CAST(PARSENAME(@IP ,3) AS INT) <=CAST(PARSENAME(IPHigh ,3) AS INT) AND CAST(PARSENAME(@IP ,2) AS INT) <=CAST(PARSENAME(IPHigh ,2) AS INT) AND CAST(PARSENAME(@IP ,1) AS INT)<=CAST(PARSENAME(IPHigh ,1) AS INT)
    

    AS Per @Ed Haper Comment Cast is needed.
