Whatever the case may be you should understand the implications of student loans and how repaying them can affect not only your current credit situation, but also your future financial worthiness. In this article we’ll examine some of the tips, tricks and warning as

h to IPv6 reserved addresses - any address that begins with "0000 0000" is an IPv6 reserved address. One of these is the IPv6 loopback address, and this will give you some practice with your zero compression!

Public Relations: Avoid These 5 Press Release Blunders
A successfully placed press release can lead to an overwhelming amount of free publicity. In fact, being mentioned in an article -- or better yet, being the focus of one -- can sometimes deliver better advertising results than buying an expensive ad in the same publication. That’s because people put their advertising filters away when they read articles. They don’t

Learning IPv6 is paramount in your efforts to pass the BSCI exam and go on to earn your CCNP, and it's going to help in your real-world networking career as well. IPv6 can be confusing at first, but it's like anything else in Cisco or networking as a whole - learn one part at a time, master the fundamentals, and you're on your way to success. In today's article we're going to take a look at IPv6 address types.

In IPv4, a unicast address is simply an address used to represent a single host, where multicast addresses represent a group of hosts and broadcasts represent all hosts.

In IPv6, it's not quite that simple. There are actually different types of unicast addresses, each with its own separate function. This allows IPv6 to get data where it's supposed to go quicker than IPv4 while conserving router resources.

IPv6 offers two kinds of local addresses, link-local and site-local. Site-local addresses allow devices in the same organization, or site, to exchange data. Site-local addresses are IPv6's equivalent to IPv4's private address classes, since hosts using them are able to communicate with each other throughout the organization, but these addresses cannot be used to reach Internet hosts.

Site-local and link-local addresses are actually derived from a host's MAC address. Therefore, if HostA has HostB's IPv6 address, HostA can determine HostB's MAC address from that, making ARP unnecessary.

Link-local addresses have a smaller scope than site-local. Link-local addresses are just that, local to a physical link. These particular addresses are not used at all in forwarding data. One use for these addresses is Neighbor Discovery, which is IPv6's answer to ARP.

You can identify these and other IPv6 addresses by their initial bits:

001 - Global address

(first 96 bits set to zero) - IPv4-compatible address

1111 1111 – Multicast

1111 1110 11 - Site local

1111 1110 10 - Link Local

As a future CCNP, you're more than familiar with the reserved IPv4 address classes. You also know that they're not exactly contiguous. The developers of IPv6 took a structured approach to IPv6 reserved addresses - any address that begins with "0000 0000" is an IPv6 reserved address. One of these is the IPv6 loopback address, and this will give you some practice with your zero compression!

Do You Remember Skinny Dipping?
Skinny dipping, oh yeah, I remember skinny-dipping. I’ve always felt lucky that I was born in 1961. It meant that I was able to catch the tail end of the baby boomers. And that meant that I got to grow up in the seventies. It was a great time – there was skinny-dipping, rock n roll, good times, and living life to the fullest.So let’s talk about skinny-dipping.

When choosing a host for your website you should seriously consider the economic and strategic benefits for your internet business of selecting a host that will allow you to host unlimited domains on your account. This benefit may prove to be of much greater value to you than the small differences between hosts in monthly fees, monthly bandwidth transfer allowances, storage capacity, domain name costs and other heavily advertised hosting features.

Tapping into your home equity or your retirement account to pay off credit card or other unsecured debt is always a bad idea. It seams like more and more lenders and other financial services companies are encouraging you to do both. Don’t do it and here’s why:

Whatever reason you may have for wanting to start a home based business you will not be sorry for making this decision. You might have to work much harder in the beginning stages of establishing your venture than you ever did working for an employer, but once you have got it running smoothly you will be so happy that you took the plunge and started working for yourself.
