ChoosingaStaticIPAddress
ForaNetworkAdministeredbyaNetworkAdministrator
IfyouareaddingtheserialENETinterfacetoanexistingEthernet
network,youmustchooseIPaddressescarefully.Contactyournetwork
administratortoobtainanappropriatestaticIPaddressforyourserial
ENETinterface.Also,havethenetworkadministratorassigntheproper
subnetmask,gateway,andDNSserveraddresses.
ForaNetworkwithoutaNetworkAdministrator
IfyouareassemblingyourownsmallEthernetnetwork,youcanchoose
yourownIPaddresses.ThesubnetmaskdeterminestheIPaddress
format.Youshouldusethesamesubnetmaskasthecomputeryouare
usingtoconfigureyourserialENETinterface.Ifyoursubnetmaskis
255.255.255.0,thefirstthreenumbersineveryIPaddressonthenetwork
mustbethesame.Ifyoursubnetmaskis255.255.0.0,onlythefirsttwo
numbersintheIPaddressesonthenetworkmustmatch.
Foreithersubnetmask,numbersbetween1and254arevalidchoices
forthelastnumberoftheIPaddress.Numbersbetween0and255are
validforthethirdnumberoftheIPaddress,butthisnumbermustbethe
sameasotherdevicesonyournetworkifyoursubnetmaskis
255.255.255.0.
Ifyouaresettingupyourownnetwork,youprobablydonothavea
gatewayorDNSserver,soyoushouldsetthesevaluesto0.0.0.0.
