You mean 'e.g.', not 'i.e.'.

There are several conventions for where in the subnet the default
router is. First and last IP address are common enough, but Cambridge
uses what I gather was a convention in (bits of?) JANET which makes
the router in a /24 be .62, which takes some getting used to.

Since 'last' IP address is a current convention, I don't think it's
sensible to complain about Red Hat's installer.

[The broadcast address is effectively standard now. What's a
'broadcast source'? I would call the address with all host bits set to
zero the 'network number'.]
