Abstract: In some embodiments, a method stores domain name system (DNS) resolution mappings from a domain name to an address in a first table. The DNS resolution mappings are intercepted from DNS responses being sent by a DNS server. The first table is sent to a manager for validation of the DNS resolution mappings. Then, a second table is received from the manager that contains validated DNS resolution mappings. The method intercepts a DNS response that includes a domain name to address resolution mapping from the DNS server and validates the domain name to address resolution mapping using a validated DNS resolution mapping in the second table.

Abstract: A computing system is configured to perform zero-trust domain name resolution. The computing system includes applications coupled to a zero-trust client. The zero-trust client is configured to receive requests for IP addresses corresponding to endpoint identifiers for internet connected endpoints. The zero-trust client includes a synthetic DNS service configured to identify synthetic IP addresses for the endpoint identifiers. The zero-trust client provides the synthetic IP addresses for the endpoint identifiers to the applications. The zero-trust client sends data traffic from the applications to a zero-trust service with the synthetic IP addresses and sends corresponding endpoint identifiers to the zero-trust service in a fashion that allows the synthetic IP addresses to be correlated to the endpoint identifiers at the zero-trust service.

Abstract: The disclosure provides an approach for seamless hand-off of data traffic in public cloud environments. Techniques are provided for activating an edge services gateway (ESG) virtual computing instance (VCI) on a new host. Prior to activating the ESG VCI on the new host, an underlay routing table is reprogrammed to associate a first IP address of a first tunnel endpoint (TEP) with a first network interface of an old host and to associate a second IP address of a second TEP with a second network interface of the new host. The routing table associates a third IP address of the ESG VCI with the first network interface. After activating the ESG VCI, a packet having as a destination address the third IP address is received at the first network interface and is encapsulated, by the first TEP, with an outer header having as a destination address the second IP address.

Abstract: Systems and methods herein provide for a proxy infrastructure. In the proxy infrastructure, a network element (e.g., a supernode) is connected with a plurality of exit nodes. At one of a plurality of messenger units of the proxy infrastructure, a proxy protocol request is received directly from a client computing device. The proxy protocol request specifies a request and a target. In response the proxy protocol request, a selection is made between one between one of the plurality of exit nodes. A message with the request is sent from the messenger to the supernode connected with the selected exit node. Finally, the message is sent from the supernode to the selected exit node to forward the request to the target.

Abstract: A packet sending method and device. The first node sets a next-hop of the routing information to a next-hop through which the first node reaches the first route source. The destination address of the routing information is the address prefix. When the second route source is superior to the first route source, the first node switches the next-hop of the routing information to a next-hop through which the first node reaches the second route source. Then, the first node adds, to a target packet, path information of a forwarding path from the first node to the second route source according to the switching operation, where a destination address of the target packet matches the address prefix. Finally, the first node forwards the target packet to the second route source through the forwarding path.
