The document provides an overview of routing protocols and IP addressing concepts. It discusses MAC addresses, IP addressing including classes and subnetting, IPX addressing, and routing fundamentals such as forwarding tables, convergence, metrics, and routing protocols. Specific protocols covered include RIP, with details on distance vector routing. The overall agenda is to introduce IP and IPX addressing, generic routing concepts, specific routing protocols, and static and default routes.
A new copyright law is being introduced in New Zealand. The government is putting the onus on ISPs to ensure that none of their users infringes copyright. It seems that if someone is accused 3 times of breaking copyright they will have their internet access withdrawn. There is no recourse to law and internet users in NZ have been protesting against this derogation of natural law.
The term ISP has been widened to include anyone providing internet access - commercial, work, school, hospital, cafe ...
DCMI Keynote: Bridging the Semantic Gaps and InteroperabilityMike Bergman
M. Bergman's presentation, 'Bridging the Gaps: Adaptive Approaches to Data Interoperabiity,' was a keynote at the DCMI's DC 2010 International Conference in Pittsburgh, PA, on October 22, 2010.
In the presentation, Bergman points to the Dublin Core Metadata Initiative as a unique and key player in plugging the semantics "gap" within the semantic Web. Some specific activities and roles are suggested.
Data-driven Applications with conStructMike Bergman
The first unveiling of conStruct, a structured content system for enabling Drupal to be driven by structured (RDF) data. conStruct also is based on the platform-independent structWSF Web services framework, the provides dataset collaboration over the Web. Presentation is from SemTech 2009.

In this networking presentation, we have covered NAT and classful Sub netting and classless sub netting using IPv4 address. we find number of hosts,total networks,first valid IP address, Last Valid Ip Address,Host ID,Network ID
IP Addressing and Subnetting
1. Write the default Masks for the Class A, Class B and Class C IP addresses.
2. How we can distinguish Class A, Class B, Class C, Class D and Class E IP addresses from each other. Write the range of first octet in decimal and Binary for all the 5 IP address classes.
3. Write the default subnet Masks for the following IP addresses:
4. Write down the three available ranges for assigning Private IP addresses recommended by IANA (Internet Assigned Number Authority).
5. A broadcast address is the one that addresses to all the hosts in any network. State that to create a broadcast address, all the bits of network ID portion or all the bits of host ID portion are set to 1? Write down the broadcast addresses of the networks to which the following IP addresses belong, write network addresses and ranges of their valid IP address too. (No subnetting).
6. Subnet Mask or Custom mask tells us that how many bits are used for Subnet ID portion and how many for host ID portion. Identify how many bits are used for sub netting in the following IP address using its subnet mask:
7. Extract the Network Addresses of the given IP addresses in question number 8, using the subnet masks given with them. (Remember that ANDing the IP address with the Mask extracts the network address from the given IP address).
8. Suppose you have a class C Network 208.94.115.0. Your task is to design a subnet scheme so that we can create 16 Network segments (subnets) within this Network. Each subnet should support 10-14 hosts.
9. Suppose you have a class C Network 220.94.115.0. Your task is to design a subnet scheme so that we can create 28 Network segments (subnets) within this Network. Each subnet should support hosts as given below.
• 2 Network Segment support 30 Hosts
• 4 Network Segment support 14 Hosts
• 8 Network Segment support 6 Hosts
• 14 Network Segment support 2 Hosts
