70-410 net mask and IPV^6

Question 1

Exemplo

50 host mask 10.10.100/24

Answer 1

2^x -2 = 
2^6=64      64 é o mais proximo de 50
x=6  (zeros)
11111111.1111111.1111111.11000000
8+8+8+2 =26
Mask 10.10.10.0/26
0000000= 7 (zeros)
111111111.11111111.11111111.11=26 (um)

1100000000=192 mask 10.10.10.192

Question 2

2^x

Answer 2

subneting
 2^6=64
2^7=128
2^8 = 256
2^9 =512
2^10 = 1024
2^ 11 = 2048
2^12 = 4096

Question 3

• Site-local

Answer 3

• Site-localLike private IPv4 addresses, site-local addresses are used within an organization’s intranet and can be reused for different sites of an organization. Site-local addresses always begin with
“fec”, “fed”, “fee”, or “fef”.

Question 4

• Link-local

Answer 4

Like Automatic Private IP Addressing (APIPA) addresses (169.254.0.0/16), link-local addresses are used on a specific link. Link-local addresses always begin with “fe80”.

Question 5

• Global addresses

Answer 5

Like public IPv4 addresses, IPv6 global addresses are globally reachable on the IPv6 portion of the Internet. Global IPv6 addresses typically begin with a “2” or a “3”.

Question 6

Exemplo

500host mask 10.10.100/24

Answer 6

2^x -2 = 
2^9=512      512 é o mais proximo de 500
x=9  (zeros)
11111111.1111111.1111110.0000000
8+8+7 =23
Mask 10.10.10.0/23
0.00000000= 7 (zeros)
111111111.11111111.1111111=23 (um)

1111110=254 mask 10.10.10.254
