I am sure that I am not the only Arpa/Milnet user who doesn't fully understand the structure of a Usenet address. I recognize that the "!" indicates the path between two hosts, but what does {decvax,unc,hao,cbosgd,seismo,aplvax,uci} mean? If anyone of those is the beginning of a path, how do we decided what is the preferred route? Jeff

I've found that the best path from ARPA-land to USENET is to always use host "seismo". If "seismo" is one of the choices given in a {} selection, like {decvax,seismo,aplvax}!crash!bang!thud or the like, then use seismo, and append "@seismo" on the end of the string. To send to the above fake address, you'd send to "seismo!crash!bang!thud@seismo.ARPA" (your own mailer will probably put that ".ARPA" on the end automatically). If all you have is a string of exclamation-point addresses, like zap!oof!bletch!crud then again surround them with "seismo"s, like: seismo!zap!oof!bletch!crud@seismo in your "To:" field. This seems to work just about all the time... Pragmatically, Will Martin -------

The meaning of a usenet address (e.g. in my signature) with {a,b,c}!d!e is that any of the sites a, b or c are "good" starting points, normally a "well-known" backbone site within usenet. If you know how to get to one of these, you have the last parts of the route, which can be the hardest to learn otherwise (especially with the current rate of growth of number of sites). -- Darrel J.
