 The number of nodes her network you're limited to one through 254 and the
 node portion of the address gives you 254 node addresses because 255
 issues for broadcasters you’re more limited on the number I've noted
 dresses get but there are act on Class C network address is out there the
 last two 224 the 239 multi casting which is what a multicast is an IP are
 abroad type of broadcasts not necessary broadcast Coast everybody a
 multicast goes to a group nodes that are listening for messages one
 particular multicast address like OSPF on a router sends out its all spy
 updates it sends them the multicast addresses to 24 to 0 to 0 about 5 and
 all the other routers are listening for those multicast updates on tatty
 4005 a good example multicast address news in class P is used for research
 that's240 in a but those are the basic class boundaries and you should be
 comfortable with these because that's going to tell us something because
 if I have a twelve-year and I'm using this subnet mask that means I've got
 whole bunch of subnets I've got a thing at sixty-five
 [http://642-813dump.com/ 642-813] thousand plus some that site got here if
 I'm using a Class C network address sick 2001 and I'm using the same
 subnet mask I don't have any sudden it's because class C uses the first
 three octets for network portion Class AA only uses the first octet for
 network that way when I is a classy address I get two octets subnets
 classy address I don't get any summits at this mass because this is the
 default mask that's my starting point so it's very important to build the
 look the first number in an address build termini what class at the party
 because that tells you what the starting point was for the subnet mask how
 many potential summit you have based on the new subnet mask let's go back
 to that said noting that we were doing are actually going to subnet
 something Council hearing or we were and a network with 11 all the way up
 to 11 subnets were using the network address 12 000 which is a Class A
 which is slashing are255 does /urn does /urn as a rock and when I’m going
 to need to deal with the seven masses are many change it from because with
 the 12.
