The document discusses IP addressing and the classification of IP addresses. It explains that IP addresses are made up of 4 octets and broken into classes A through E. It provides details on each class, including how many bits are used for the network and host portions and the number of available networks and hosts. Special addresses like private IP addresses that start with 10, 172.16, or 192.168 are also discussed.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

2. The 32-bit IP address is broken up into 4 octets, which are arranged into a dotted-decimal notation scheme. An octet is a set of 8 bits & not a musical instrument. Example of an IP version 4: 172.64.126.52 Peter Smith 2 Octets
3. IP addresses are divided into 5 classes, each of which is designated with the alphabetic letters A to E. Class D addresses are used for multicasting. Class E addresses are reserved for testing & some mysterious future use. Peter Smith 3 IP Address Classes
4. The 5 IP classes are split up based on the value in the 1st octet: Peter Smith 4 IP Address Classes
5. Using the ranges, you can determine the class of an address from its 1st octet value. An address beginning with 120 is a Class A address, 155 is a Class B address & 220 is a Class C address. Peter Smith 5 IP Address Classes
6. Peter Smith 6 Network & Host Representation By IP Address Class Class Octet1 Octet2 Octet3 Octet4 Class A Network Host Host Host Class B Network Network Host Host Class C Network Network Network Host Are You the Host or the Network? The 32 bits of the IP address are divided into Network & Host portions, with the octets assigned as a part of one or the other.
7. Each Network is assigned a network address & every device or interface (such as a router port) on the network is assigned a host address. There are only 2 specific rules that govern the value of the address. Peter Smith 7 Are You the Host or the Network? (Cont.)
8. A host address cannot be designated by all zeros or all ones. These are special addresses that are reserved for special purposes. Peter Smith 8 Are You the Host or the Network? (Cont.)
9. Class A IP addresses use the 1st 8 bits (1st Octet) to designate the Network address. The 1st bit which is always a 0, is used to indicate the address as a Class A address & the remaining 7 bits are used to designate the Network. The other 3 octets contain the Host address. Peter Smith 9 Class A Addresses
10. There are 128 Class A Network Addresses, but because addresses with all zeros aren’t used & address 127 is a special purpose address, 126 Class A Networks are available. Peter Smith 10 Class A Addresses
11. There are 16,777,214 Host addresses available in a Class A address. Rather than remembering this number exactly, you can use the following formula to compute the number of hosts available in any of the class addresses, where “n” represents the number of bits in the host portion: (2n – 2) = Number of available hosts Peter Smith 11 Class A Addresses
12. For a Class A network, there are: 224 – 2 or 16,777,214 hosts. Half of all IP addresses are Class A addresses. You can use the same formula to determine the number of Networks in an address class. Eg., a Class A address uses 7 bits to designate the network, so (27 – 2) = 126 or there can be 126 Class A Networks. Peter Smith 12 Class A Addresses
13. Class B addresses use the 1st 16 bits (two octets) for the Network address. The last 2 octets are used for the Host address. The 1st 2 bit, which are always 10, designate the address as a Class B address & 14 bits are used to designate the Network. This leaves 16 bits (two octets) to designate the Hosts. Peter Smith 13 Class B IP Addresses
14. So how many Class B Networks can there be? Using our formula, (214 – 2), there can be 16,382 Class B Networks & each Network can have (216 – 2) Hosts, or 65,534 Hosts. Peter Smith 14 Class B IP Addresses
15. Class C addresses use the 1st 24 bits (three octets) for the Network address & only the last octet for Host addresses.the 1st 3 bits of all class C addresses are set to 110, leaving 21 bits for the Network address, which means there can be 2,097,150(221 – 2) Class C Networks, but only 254 (28 – 2) Hosts per Network. Peter Smith 15 Class C IP Addresses
17. A few addresses are set aside for specific purposes. Network addresses that are all binary zeros, all binary ones & Network addresses beginning with 127 are special Network addresses. Peter Smith 17 Special Addresses
19. Within each address class is a set of addresses that are set aside for use in local networks sitting behind a firewall or NAT (Network Address Translation) device or Networks not connected to the Internet. Peter Smith 19 Special Addresses
20. A list of these addresses for each IP address class: Peter Smith 20 Private IP Addresses
