Route53---NS, Hosted zones and record sets, TLD
how name will be converted into ip address ?(name resolution)
why we need external storage ?

------------------------------
CDN- Content delivery network
machine never understands names and it requires ip address for the n/w communication.
what is the need of n/w ?
n/w--data sharing
servers always use physical communication with the ethernet/NIC card
every nic is have ip address.
=============================================
Day:3
IP address- Private ip and public ip(ifconfig/ipconfig)
DNS(nslookup,host,digi)
port ( netstat,lsof)
ssh ( ssh,telnet)
RDS,mstsc
Remote login
Operating systems and flavours
lab:block website
find your gateway and ip address and subnet mas
ping 10 websites(3 wront and 7 success) and increase the packet count
nslookup for 10 websites(5 wrong websites and 5 success)
IP address versions:IPv4(numeric) and IPV6(128bit---alpha numeric)
IPV4(32 bit)
(0-255)
xxx.xxx.xxx.xxx
Computer---------------Router/Nat Gateway/Nat Instance/Proxy(fwd)--------------------------internet
if servers want to go to internt we use proxy or nat gateway
ip addresses public and private
Private ip address
10.xx.xx.xx

it can be duplicate based on network zone.
private ip adress area called a intranet.
Privaete websites always have private ip.
Public ip
other than private series
public ip address area called a internet(0.0.0.0).
can be accessed from anywhere and unique(no duplicate)
public websites will have public ip address.
To know ipaddress of your website/hostname/servername
nslookup <websitename>/<hostname>/<servername>
www.google.com ---------------------->DNS Server(NS)----www.google.com | 172.217.xxx and ipv6
ping used to check up <websitename>/<hostname>/<servername> or responding or not.
ping will send icmp(Internet chat msg protocal) packets.
in AWS ping is disabled by default.
in windows ping will send 4 icmp
in unix its unlimited
www.google.com
Request format:
protocal://<websitename>/Hostname/servername/IPaddress :<port>/contextroot
mandatory: protocal
ipaddress
port
ex:1
https://www.google.com/
protocal: https
websitename: www.google.com
port: 443
contextroot: /
http://www.eenadu.net/
ex:-2
protocal: http
websitename: www.eenadu.net
port: 80
contextroot: /
port : numerical number and assigned to a service in your machine.
to access that service you have to use port number.

Block the websites
Review of yesterday and previous day
AWS account login
basics of software installation(.exe,.bat,rpm,yum,apt-get)
Basics of windows, login and admin login
Normal user and system admin
Block the website: C:\Windows\System32\drivers\etc\hosts

www.eenadu.net------hosts-----ISP---DNS(tld)---peerDNS----destination server
protocal: http
port:80
websitename : www.eeandu.net---127.0.0.1
open the notepad in administrator mode-->file-->open-->C:\Windows\System32\drivers\etc\hosts
Connection refused: you have ip address and you are reaching to server and your port not listening.
the service on the port number stopped.
DNS_PROBE_xxx: wrong dns name or dns entry not found(check with nslookup)
Windows: how do you install the software ?
browser--->internet--->Repository--software/package/artifacts(store all the packages)------>download into your local-->
repository/artifactory--software packages storing location.
.exe (executable)--windows-GUI-Graphical user interface/CLI(command line interface)
.bat(batch)

lab: create one user in your laptops with devops name and put a password for that user.
login with that user into system and see desktop and compare with the previouosly used user.
cd - change directory
cd .. ( come back one directory back)
cls (clear screen) -- clear or ctrl+l(unix)
any os during installation user will be created(administrator/Power user/root user)
Administrator can create multiple users(normal users).
port numbers: 1-1024 port admin users
1025 to 35k -- normal users.
