Internet Addressing
•IP address is a 32 bit integer
•Refers to interface rather than host
•Consists of network and host portions
• Enables routers to keep 1 entry/network instead of 1/host
•Class A, B, C for unicast
•Class D for multicast
•Class E reserved
•Classless addresses
•Written as 4 octets/bytes in decimal format
•E.g. 134.79.16.1, 127.0.0.1

Internet Class-based addresses
• Class A: large number of hosts, few networks
• 0nnnnnnn hhhhhhhh hhhhhhhh hhhhhhhh
• 7 network bits (0 and 127 reserved, so 126 networks), 24 host bits (>
16M hosts/net)
• Initial byte 1-127 (decimal)
• Class B: medium number of hosts and networks
• 10nnnnnn nnnnnnnn hhhhhhhh hhhhhhhh
• 16,384 class B networks, 65,534 hosts/network
• Initial byte 128-191 (decimal)
• Class C: large number of small networks
• 110nnnnn nnnnnnnn nnnnnnnn hhhhhhhh
• 2,097,152 networks, 254 hosts/network
• Initial byte 192-223 (decimal)
• Class D: 224-239 (decimal) Multicast [RFC1112]
• Class E: 240-255 (decimal) Reserved

Subnets
•A subnet mask is applied to the host bits to
determine how the network is subnetted, e.g. if
the host is: 137.138.28.228, and the subnet
mask is 255.255.255.0 then the right hand 8
bits are for the host (255 is decimal for all bits
set in an octet)
•Host addresses of all bits set or no bits set,
indicate a broadcast, i.e. the packet is sent to all
hosts.

Creative IP address allocation
• Class A addresses 64 – 127 reserved
• Handle on individual basis
• Class B only assigned given a demonstrated need
• Class C
• divided up into 8 blocks allocated to regional authorities
• 208-223 remains unassigned and unallocated
• Three main registries handle assignments
• APNIC – Asia & Pacific www.apnic.net
• ARIN – N. & S. America, Caribbean & sub-Saharan Africa
www.arin.net
• RIPE – Europe and surrounding areas www.ripe.net

What do we learn from Ping “testing”
• Host reachable
• Host may respond to ping but not be running services
• Round trip timing
• Lost packets
• Packet reordering duplicate packets
• Example:
13cottrell@noric05:~>ping -c 4 lhr.comsats.net.pk
PING lhr.comsats.net.pk (210.56.16.10) from 134.79.125.205 : 56(84) bytes of data.
64 bytes from lhr.comsats.net.pk (210.56.16.10): icmp_seq=0 ttl=242 time=716.962 msec
64 bytes from lhr.comsats.net.pk (210.56.16.10): icmp_seq=1 ttl=242 time=720.375 msec
64 bytes from lhr.comsats.net.pk (210.56.16.10): icmp_seq=2 ttl=242 time=725.907 msec
64 bytes from lhr.comsats.net.pk (210.56.16.10): icmp_seq=3 ttl=242 time=710.734 msec
--- lhr.comsats.net.pk ping statistics ---
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max/mdev = 710.734/718.494/725.907/5.566 ms
