Why windows XP sends messages with 239.255.255.250 destination IP address?

We can see few packets destined to 239.255.255.250 IP address in Wireshark. They are:

1) SSDP Messages

2)  IGMP messages destined to 239.255.255.250

SSDP protocol is used to discover Upnp (Plug and play) devices in network. When we enable or disable the network interface, you can observe these messages.
