Actually, docker uses the netfilter firewall to make sure the service is available. lsof wouldn't tell you anything. Try running. iptables -L -t nat ip6tables -L -t nat It is possible that the container doesn't listen to the specified port however.

Optional multiple front-end configurations which enable a single load balancer to use multiple IPv6 public IP addresses- the same frontend protocol and port can be reused across frontend addresses. Optional IPv6 ports can be reused on backend instances using the Floating IP feature of load-balancing rules Aug 05, 2010 · Using an IPv4 address, the syntax would be 10.0.0.1:45001 where 45001 is the custom port. But since IPv6 addresses have embedded colons, it seems like the colon used to distinguish the port from the IP address is mis-parsed. The Port Scan tool scans an IP address for open or closed TCP ports. It will scan the 13 most used ports like FTP, SSH and WWW. For security reasons it can only execute a port scan on your own public IP address (IPv4 and IPv6). Just hit the Go button to start scanning. Nov 11, 2019 · NAT-PT for IPv6. NAT—PT is an IPv6-to-IPv4 translation mechanism, as defined in RFC 2765 and RFC 2766, that allows IPv6-only devices to communicate with IPv4-only devices and vice versa. ipv6 unicas-routing reference only to the routing part of the IPv6. You don't have any command related to "ipv6" in your configuration? I have a 28xx with 12.4 (24) T6 and : show udp. Proto Remote Port Local Port In Out Stat TTY OutputIF. 17 --listen-- 172.30.32.1 1698 0 0 1 0 IPV6_V6ONLY (since Linux 2.4.21 and 2.6) If this flag is set to true (nonzero), then the socket is restricted to sending and receiving IPv6 packets only. In this case, an IPv4 and an IPv6 application can bind to a single port at the same time. P4PORT protocol value Behavior in IPv4/IPv6 or mixed networks Use tcp4: behavior, but if the address is numeric and contains two or more colons, assume tcp6: If the net.rfc3484 configurable is set, allow the OS to determine which transport is used.

Jul 20, 2017 · This example disable IPv6: AddressFamily inet The default is any. inet6 means IPv6 only. On the client side, logging in over IPv6 networks is the same as IPv4, except you use IPv6 addresses. This example uses a global unicast address in the private LAN address range: $ ssh carla@2001:db8::2

IPv6-enabled clients will use IPv6 in preference to IPv4. If a client finds both AAAA and A records for a hostname, it will attempt to connect via IPv6 first. If a service is advertised in the DNS with a AAAA record, but is not listening on IPv6, clients will experience delays as their IPv6 connection attempts must timeout.

Port numbers. DHCPv6 uses UDP port number 546 for clients and port number 547 for servers. Identifiers DHCP unique identifier. The DHCP unique identifier (DUID) is used by a client to get an IP address from a DHCPv6 server. It has a 2-byte DUID type field, and a variable-length identifier field up to 128 bytes. TCP Port Scanner. With this online TCP port scanner you can scan an IP address for open ports. Use this TCP port scan tool to check what services (apache, mail, ssh, ftp, mysql, telnet, dns) are running on your server, test if your firewall is working correctly, view open TCP ports. IPv6-test.com is a free service that checks your IPv6 and IPv4 connectivity and speed. Diagnose connection problems, discover which address(es) you are currently using to browse the Internet, and what is your browser's protocol of choice when both v6 and v4 are available. The port scanner tool will provide you with information regarding valid methods of connecting to a network. Scan your network for open ports and determine if those open ports need to be closed to provide more network security and less vulnerabilities.
