CCNA Recap: IPv6



IPv6 Router Solicitation

* FF02::2

IPv6 uses an Extension Header.
A Router Solicitation w/ IPv6 looks like FF02::2

Valid IPv6 Addresses




* Eight groups of
* four hexidecimal digits that
* represent sixteen bits =
* two octects

Ipv6 Router Advertisement
* Type 134
* Prefix length must be 64 bits (4 groups)


The below has the feeling of being directly copied from somewhere, but I'm not finding where.

For the purpose of applying an access list to a particular interface, the ipv6 traffic-filter  IPv6 command is equivalent to the access-group IPv4 command. The direction in which the traffic is examined (in or out) is also required.


IPv6 address to MAC address resolution is performed through the exchange of ICMPv6 neighbor discovery packets comprised of neighbor solicitation and neighbor advertisement packets. Unless these packets are permitted on a router interface, the interface will not be able to perform MAC address resolution.

The original notes continue


IPv6 Anycast
* one to nearest comm model
* same address for multiple devices
* delivery of packets to the group interface closest to the sending device


EMPLOYERS: This is me reviewing concepts I have been tested on and passed in the past.

Azure Networking Options - Core Cloud Services

I have done a lot of AWS things on here. Time to give Azure some attention. After all, since employers don't think Cisco or COMPTIA certifications are important, maybe Microsoft ones are?

First, let's really think about why these are the two biggest cloud services providers in the world:

They've been doing internet things for a long time.Amazon launched in 1995, a virtual bookstore.
Microsoft, well, you know. 

They've lived, breathed, and frankly, created, infrastructure that we use today, that they're selling to us today. Of course the Store of Everything and the Company of Everything would encourage us to put everything in their hands.

Also: Azure has a lot less silly names for modules. Important. I appreciate straightforwardness.


I said 'a lot less', not '100% sensible names'

Microsoft has a clear set of Azure Fundamentals that anyone can interact with. Let's talk about networking basics, basically to say, again, "Hi, employers, I have an …

Grace Hopper Celebration 2019 (GHC19)

From Aicha Evans' speech at the Keynote.
September 6th - I receive an email from Anita B Organization, saying "We read your application, we like your website, and here's a free ticket to GHC 2019 in Orlando, Florida!"


After a few more questions, it seemed everything was on the up and up, and so I accepted - and that's what this post is about!

For those who don't know, Grace Hopper Celebration is the largest gathering of Women in Technology in the world.

On a personal note, This is the first trip I've taken without my parents. Sure, they've left me behind to go on vacations, but I've never left them. I was totally worried! But you know what happened?

I met a lot of cool people in Orlando, learned a lot of neat things, and had a blast just walking around airports for upwards of 8 hours.

New Delta Sky Club on Wikimedia I really, really love airports! And I survived.

I know in the past, I've wormed my way out of jobs despite being interested simpl…

Search and Infiltrate: How to Deeply Investigate a Company's People

Latest Update - 12/2/2019


This is a bit of an impromptu post after reading this article.

I had a small thread about this on Twitter, a blog post is a lot better to get the information out in a clear way.

Have you ever used Recruitin.net, came across a group of people who match Your Dream Company, Dream Location, and do your Dream Job on LinkedIn...and they're not active?

What was the POINT, am I right?  A place for professionals to network, but they're not active ...because they have a job to do! You want to be like that!

Unfortunately, in this day and age, unless you have a 'relationship' with someone, they're not going to help you.

Hm. 

(Note: 'relationship' is different than relationship).

I'm not here to talk bad about recruiters - They have a difficult job, I know I couldn't do it! - And even they want a relationship before they place you somewhere, competency be damned.

What do you do instead?
