It became clear (e.g. https://github.com/bitcoin/bitcoin/issues/21351#issuecomment-811004779) that a CLI command returning the number of addresses the node knows per network (with a tor v2 / v3 breakdown) would be very helpful. This patch adds that. `-addrinfo` is useful to see if your node knows enough addresses in a network to use options like `-onlynet=<network>`, or to upgrade to the upcoming tor release that no longer supports tor v2, for which you'll need to be sure your node knows enough tor v3 peers. ``` $ bitcoin-cli --help | grep -A1 addrinfo -addrinfo Get the number of addresses known to the node, per network and total. $ bitcoin-cli -addrinfo { "addresses_known": { "ipv4": 14406, "ipv6": 2511, "torv2": 5563, "torv3": 2842, "i2p": 8, "total": 25330 } } $ bitcoin-cli -addrinfo 1 error: -addrinfo takes no arguments ``` This can be manually tested, for example, with commands like this: ``` $ bitcoin-cli getnodeaddresses 0 | jq '.[] | (select(.address | contains(".onion")) | select(.address | length <= 22)) | .address' | wc -l 5563 $ bitcoin-cli getnodeaddresses 0 | jq '.[] | (select(.address | contains(".onion")) | select(.address | length > 22)) | .address' | wc -l 2842 $ bitcoin-cli getnodeaddresses 0 | jq '.[] | .address' | wc -l 25330 ``` ACKs for top commit: laanwj: Tested ACK 06c43201a714b0426cc68b2fd5c681e5df10af99 Tree-SHA512: b668b47718a4ce052aff218789f3da629bca730592c18fcce9a51034d95a0a65f8e6da33dd47443cdd8f60c056c02696db175b0fe09a688e4385a76c1d8b7aeb
