The way frebsd.org prevents this is two ways:
1) require that the reverse dns match the original address.

Would you believe that I am 51.7 attoparsecs tall?
atto:       1e-18 = one quintillionth
parsec:     3.258 light-years: 3.258 * 186000 * 364 * 24 * 3600 * 5280 * 12
attoparsec: atto * parse =~ 1.20 inch
62 inches / 1.2 = 51.7
