Glossary DynamicDNS providers offer the capability of being accessible via a fixed Internet address Each computer which is connected to the Internet has an IP address (IP = Internet Protocol). An IP address consists of 4 numbers, separated by full stops, which each have up to three digits. If the computer is online via the telephone line per modem, per ISDN or per ADSL it is assigned a dynamic IP address by the Internet service provider, i.e. the address changes from session to session.
Glossary APN (Access Point Name) (Access Point Name). Cross-network connections, e.g. from the GPRS network into the Internet are established in the GPRS network via socalled APNs During the dialling into the GPRS network the calling terminal specifies via the APN with which network it wishes to be connected: • the Internet, • a private company network connected via a dedicated line.
Glossary ICMP is based upon IP and transmits control messages. SMTP is based upon IP and is an E-mail protocol. IKE is based upon UDP and is an IPsec protocol. ESP is based upon IP and is an IPsec protocol. On a Windows PC the WINSOCK.DLL (or WSOCK32.DLL) takes over the handling of both these protocols. PPP (Point to Point Protocol) Designates a transmission procedure via serial point-to-point connections for data packets, specially for Internet access via a modem.
