 Windows Internet Name Service (WINS) is a legacy name resolution service that maps NetBIOS names to IP addresses. Officially, it's outdated and largely obsolete. DNS was supposed to replace WINS functionality. However, Microsoft has not officially deprecated WINS. WINS may still be necessary for some Windows LAN browsing functions on old Windows versions. Windows Internet Name Service (WINS) is a legacy name resolution service that maps 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. **Reduce Packet Size:** //udhcpc// (the DHCP client FreshTomato uses to obtain a WAN IP address) has a problem.

-The extra bytes appeared to be entirely padding, and therefore unnecessary.  FreshTomato developers eliminated the padding, reducing udhcpc's DHCP discovery packet size to 331 bytes. This 331 byte size eventually became the default setting. As a result, udhcpc can successfully obtain a DHCP lease from an ISP with DHCP relays. However, some users may not be able to obtain a WAN IP address unless they disable this feature.
