A quick micro benchmark shows that we can completely eliminate allocation (and by extension GC) by splitting the IP string up into 4 ints.

[Benchmark]
public UnfilteredClass TestUnfilteredClass()
{
    UnfilteredClass unfiltered = new UnfilteredClass();
        
    for (int i = 0; i < 10000; i++)
    {
        unfiltered = new()
        {
            Id = 1,
            Filtered = 1,
            Ip = "127.0.0.1",
            Port1 = 80,
            Port2 = 443,
            ResponseCode = 1
        };
    }
        
        return unfiltered;
    }
    
[Benchmark]
public UnfilteredStruct TestUnfilteredStruct()
{
    UnfilteredStruct unfiltered = new UnfilteredStruct();
        
    for (int i = 0; i < 10000; i++)
    {
        unfiltered = new()
        {
            Id = 1,
            Filtered = 1,
            Ip1 = 127,
            Ip2 = 0,
            Ip3 = 0,
            Ip4 = 1,
            Port1 = 80,
            Port2 = 443,
            ResponseCode = 1
        };
    }
        
    return unfiltered;
}
