<DIV dir=ltr><FONT face=Arial color=#000000 size=2>We take a slightly different
approach, assigning V6 to EDU institutions within .za.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>Our rule is simple, we assign /48s on /44
boundaries, and where institutions have more than one physical campus they can
have more than a /48. So if I look at some of our institutions where they
have 4 campuses for example, I'd assign them a /46. The maximum allocation
an institution can have is a /44 though.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>We do this to allow for better route
aggregation within the institutions inter-campus networks, allowing them to
assign /64s per lab/network segment, and aggregating back to a single /48 per
physically diverse campus.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>I know this strategy is a little
contrarversial, but its certainly worked well for us so far.</FONT></DIV>

According to the ARIN documentation we've read, the standard <BR>>
