I'm not sure that was ever advertised. EP.NET runs a  
registry for exchange points and other people that Bill feels like  
helping out and assigns from that number range; since the /16 covers  
many varied applications and organisations all over the planet, it  
seems unlikely that a /16 would do anything useful.

I have no problems reaching FLAG.EP.NET (, DOT.EP.NET  
(, both of which live in subnets numbered from and administered by EP.NET directly.

A quick RIS query suggests that none of the RIS probes have ever seen  
an advertisement

There are a number of prominent DNS servers numbered within; however, for various reasons a noticeable number of  
network operators take the position that all routes within that /16  
are necessarily bogons, since it was originally designated for use in  
numbering exchange-point fabrics and those blocks ought properly not  
be advertised.

I take no philosophical position on any of that (it's far too sunny  
and verdant here to form that kind of opinion here this afternoon),  
and in a similar vein apologies for any historical inaccuracies I may  
have inferred above. However, from a purely operational perspective,  
you may want to check that the specific subnets of that  
you are interested in have not been filtered by your transit providers.
