Yes, I didn't mention those because class d is reserved for multicast and class E is listed as experimental, but thanks for bringing them up, because now we've covered the entire range of IP's in ip4. The class E addresses only go until 254.255.255.255; however, because 255.0.0.0 is blocked off, and as already mentioned: 255.255.255.255 is broadcast.

Subject: Re: private vs. public IP addresses There are actually 5 classes of ips. Class a, b, and c are the ones used on the internet as a whole, and those ips have already been mentioned here. Class D has a 224.something range of ips that are considered private as well. However, this is hardly a consideration, since class D addresses are used strictly for multicasting purposes, and it's likely you'll never need one. Then, there's class E addresses. These start at 240, and there is one of these reserved for private use too, though again, I don't know what it is. Class E addresses are for experimental purposes, and are also generally multicast addresses. Again, you'll probably never see one of these ips on any network, and especially not on the internet. But, they are there, and are used occasionally, even if we don't encounter them. _______________________________________________ Speakup mailing list Speakup at braille.uwo.ca http://speech.braille.uwo.ca/mailman/listinfo/speakup
