 Windows Internet Name Service (WINS) is a legacy name registration and resolution service which maps computer NetBIOS names to IP addresses. Officially, WINS is outdated and largely obsolete. DNS was supposed to have replaced WINS functionality. However, Microsoft has not officially deprecated WINS. WINS may still be necessary for some Windows LAN browsing functions, especially on old Windows versions. Windows Internet Name Service (WINS) is a legacy name registration and resolution service which maps computer NetBIOS names to IP addresses.

 **Reduce Packet Size:** //udhcpc// (the DHCP client FreshTomato uses to obtain a WAN IP address) has a problem. It has a DHCP discovery packet size 590 bytes long. However, DHCP relay servers can only handle DHCP discovery packets up to 576 bytes. If there are DHCP relay servers between your FreshTomato router and your Internet provider's DHCP server, FreshTomato might fail to acquire a DHCP lease on the WAN interface.  The extra bytes appeared to be entirely padding, and not necessary.  FreshTomato developers eliminated the padding, which reduced udhcpc's DHCP discovery packet size to only 331 bytes. This 331 byte size eventually became FreshTomato's default setting. This way, udhcpc can successfully obtain a DHCP lease from a provider which might have DHCP relays. However, some users may not be able to obtain a WAN IP address unless they disable this feature.
