IPv6 was initially not natively available on this connection. IPv6 was tunneled via
chzrh02.sixxs.net (on-net at AS13030). The IPv6 server endpoint runs on a virtualized platform, with
slightly less than bare-bones throughput. Shortly thereafter, native IPv6 was configured on the

**Term** | **Description**
-------- | ---------------
ONT | **optical network terminal** - The ONT converts fiber-optic light signals to copper based electric signals, usually Ethernet.

ONT | **optical network terminal** - The ONT converts fiber-optic light signals to copper based electric signals, usually Ethernet.
OTO | **optical telecommunication outlet** - The OTO is a fiber optic outlet that allows easy termination of cables in an office and home environment. Installed OTOs are referred to by their OTO-ID.
CARP | **common address redundancy protocol** - Its purpose is to allow multiple hosts on the same network segment to share an IP address. CARP is a secure, free alternative to the Virtual Router Redundancy Protocol (VRRP) and the Hot Standby Router Protocol (HSRP).
SIT | **simple internet transition** - Its purpose is to interconnect isolated IPv6 networks, located in global IPv4 Internet via tunnels.
STB | **set top box** - a device that enables a television set to become a user interface to the Internet and also enables a television set to receive and decode digital television (DTV) broadcasts.

GRE | **generic routing encapsulation** - a tunneling protocol developed by Cisco Systems that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links over an Internet Protocol network.
L2VPN | **layer2 virtual private network** - a service that emulates a switched Ethernet (V)LAN across a pseudo-wire (typically an IP tunnel)
DHCP | **dynamic host configuration protocol** - an IPv4 network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers.
