Once the bit boundary is found, the subnet mask is derived by marking all consecutive matching bits with 1. Finally, as demonstrated earlier, the network address all 0s and broadcast address all 1s are easily deduced in the host portion. Example: Find the common subnet between As shown in the table, the two IP addresses have a matching bit pattern until the 19 th bit.
That is the bit boundary that dictates the network prefix. The common network for the two IP addresses is It is a common misconception that a wildcard mask is the inverse of a subnet mask.
True, often it is. However, there is no absolute dependence between subnet masks and wildcard masks in access lists. This fundamental relation between subnet masks and wildcard masks leads to the false notion that the two are directly dependent on each other, which is not true. Essentially, wildcard masks are simply matching against individual bits , 0 signifying that the compared bits must match, and 1 denoting indifference in the value. A wildcard mask does not have to be engineered from a subnet mask.
But be warned that this fundamental logic enables the creation of evil bit patterns, and as a consequence, diabolic matching scenarios.
Again, I will apply color coding to clarify the output. The wildcard mask 0. Wildcard Mask. Will IP address As long as the other bits the first 24 bits between two IP addresses are equal, there is a match.
IP address How about IP address Will it match the ACL statement? Because the IP address does not comply with the ACL rule that the first 24 bits must match. The 22 nd bit breaks the sequence. Not so easy anymore, right? Which IP addresses will that statement match? The following table lists all the possible IP addresses that will be matched by the statement:. The statement matches only four options, which are every combination that a 2-bit sequence can produce.
Marking only two bits as interesting results in this limited scope. But what does it match? The following table includes some not all! possible IP addresses that fall within the boundaries of the ACL statement. If you want, you can try to find the rest on your own. Contrary to what many of you might think, this is a valid configuration, and a router happily accepts the required commands. Router show access-list. Standard IP access list 6. Luckily, such access-list statements are seldom, if ever, used.
Regardless, it is imperative to be aware of this fundamental ACL processing logic, and understand that such wickedness can exist. As proven in the previous examples, wildcard masks are truly designed to match individual bits. Nothing more. Without getting into any detail, here are a few tidbits about binary numbers:.
The first usable host IP address in a subnet is always odd. The last usable host IP address in a subnet is always even. Gerson Leandro. Martin L. Wonderful and very informative blog; thanks for sharing! yes but 5 or 10 years does not matter; binary is not going away; thanks!
Please correct me if I misunderstood. Not exactly, it depends on how it's used. A wildcard mask can contain consecutive 1s. Thank you all for the lovely feedback. I'm humbled and I appreciate every bit of it. I came across a good read relating to the topics in this blog post on Cisco's website. Please check it out, here.

It took R about 30 minutes to backtest the data. The end results is a data frame Results that has the columns Predicted and Actual. We now use this data frame to make the confusion matrix. We use the table command that builds the confusion matrix. Above table shows how many predictions were correct and how many predictions were false. Did you notice the class imbalance? Class 0 has more members than classes 1 and The predictive accuracy is simple the sum of True Positive and True Negative divided by the total observations which in this case is This comes out to be As you can see the above cross table is much more detailed as compared to the first table that we made.
Watch this video that reveals a simple trick that increases the winrate. We use the Caret library to calculate the kappa statistic. Kappa is an important statistic that adjusts predictive accuracy for randomness.
Did we point out the class imbalance? Yes we did a few paragraphs above in which we pointed out that most of the observations belong to the 0 class. This class predicts price movement between 2 pips above and below the present price. So just by predicting this class the model can achieve a good predictive accuracy. Watch the video below that explains Kappa more. Above video explains how kappa can help us in take out chance from the predictive accuracy of our account.
We use the Caret library from R that does the calculation of kappa for us. Kappa for this strategy is just 0. A kappa above 0. So the model is just predicting based on chance. Watch these videos how to setup your day trading work stations. So this was it. By reading this post, you should develop a good idea how you are going to design and then test your algorithmic trading strategy.
Can we improve this algorithmic trading strategy? We can make a try. We include a few more indicators in our model and increase the pip size to 3 pips. We run the backtesting model again. It again took 30 minutes for R to do the calculations.
Below are the results,. Did we succeed now? This is precisely what we wanted. What this means is that the model is predicting based on chance. Sensitivity of the model gives the proportion of predictions that were made correctly. In the above results you can check the sensitivity of the model. You can see the model failed to correctly predict -1 and 1 class.
Specificity of a model gives the negative cases that the model correctly identify. Previous post. Next post. Skip to content In this post we will first design an algorithmic forex binary options trading strategy.

I recognize that a majority of the members in this forum are relatively new to the Cisco world, and one of the most common topics I see in the discussion threads relates to either some form of subnetting or wildcard masks. I wanted to dedicate this blog post to examining the operation of binary math, in relation to subnetting concepts and ACLs, in detail. Binary is a base-2 numeral system, which represents each numerical value using a sequence of 0s and 1s.
The binary system implements a positional notation, increasing in powers of 2. There are a number of different methods to convert from decimal into binary. Simple, effective, and most importantly, easy to learn with a bit of practice. All numbers between 0 and can be represented as an 8-bit string. All 8 bits are represented, and each placeholder marked with 1 adds its value to the converted number, while 0s are ignored. Example: Converting into binary. As is evident from the table, is equal to in binary.
Doing the conversion in the opposite direction is easier. Simply write out the bit sequence in the table as is, and sum up the placeholder values. Example: Converting into decimal. An IP address is a bit sequence, composed of four octets each octet containing eight bits.
The IP address consists of network and host portions. The network portion is dictated by the subnet mask. More specifically, the number of consecutive 1s in the subnet mask determines the length of the network portion, i. the bits in the IP address that indicate the network prefix.
All devices in a common subnet share the same network bits, and the remaining available bits are reserved for host addressing. The process of finding the network address is performed by a bitwise AND operation between the IP address and the subnet mask. For reference:.
The result of the AND operation yields the network address, or network prefix, and the remaining available bits are used to uniquely identify hosts. Example: Find the network address for IP Address. Subnet Mask. As determined by the AND operation comparing each bit position individually between the IP address and subnet mask , the network address is The address range is defined in the host portion.
The first address has all host bits set to 0 and the last address all 1s. These are not usable host IP addresses but are specifically reserved for identifying the network address 0s and broadcast address 1s for a subnet, respectively. The first usable host IP address is one higher than the network address, and the last usable host IP address is one lower than the broadcast address.
Network Address 0s. Broadcast Address 1s. As demonstrated in the above table, the network address is Therefore, the range of usable host IP addresses is It is crucial to understand that for the network and broadcast addresses all host bits must be set to either 0 or 1, respectively. An IP address can strikingly resemble a network address, when in fact, it is a valid host IP address.
Example: Can a host have the IP address Yes, it can, given a large enough IP address space for example, Network Address. Valid Host IP. Note that the requirement of all 0s or 1s in the host portion is not satisfied, i. Router show ip interface brief. Interface IP-Address OK? Method Status Protocol. Internet address is On the contrary, an IP address that might look like a valid host IP address can, in reality, be a broadcast address for a subnet.
Like the IP address If you try to configure it on a PC, you will receive the following error:. Similarly, if you try to apply a network address on the PC, the same warning message will pop up, indicating that all host bits are set to 0. A router will also not accept either IP address but is not as intuitive or descriptive about the matter.
Router config-if ip address The trick in defining a common subnet is to find the bit boundary where the two IP addresses match. Once the bit boundary is found, the subnet mask is derived by marking all consecutive matching bits with 1. Finally, as demonstrated earlier, the network address all 0s and broadcast address all 1s are easily deduced in the host portion. Example: Find the common subnet between As shown in the table, the two IP addresses have a matching bit pattern until the 19 th bit.
