  7. Netmask and Gateway • is the IP-address on the local network?? • or do I send it to the gateway 1999 Asian Women's Network Training Workshop

  8. Domain Name System 1999 Asian Women's Network Training Workshop

  9. Nameserver • converting names to IP-numbers • A-records • Type=A • Name=jca.apc.org • IP Address=210.149.85.82 • converting IP-numbers to names • PTR-records • Type=PTR • 82.85.149.210.IN-ADDR.ARPA • name=jca.apc.org 1999 Asian Women's Network Training Workshop
