c457fb144cimprove clarity and up max ipv6 ASNs (Baas) Pull request description: This PR attempts to address some of the areas of improvement raised in #17020 . Concretely, my proposed change is fairly minor but addresses the following changes to [`makeseeds.py`](https://github.com/bitcoin/bitcoin/blob/master/contrib/seeds/makeseeds.py): - Increase max seeds per ASN for IPv6 to 10 as recommended [here](https://github.com/bitcoin/bitcoin/pull/16999#issuecomment-536999544), while keeping max seeds per ASN for IPv4 at 2. - Bump `MIN_BLOCKS` to 730000. - Improved script clarity: added function types and more docs to functions, added progress indicator when performing ASN lookup, and change string formatting to better align with [bitcoin python style guidelines](https://github.com/bitcoin/bitcoin/blob/master/test/functional/README.md#style-guidelines) With the different ASN limits for IPv4 and IPv6, and the new minimum block requirement, the current stats look look like: ``` IPv4 IPv6 Onion Pass 470689 73238 0 Initial 470689 73238 0 Skip entries with invalid address 470689 73238 0 After removing duplicates 470688 73238 0 Skip entries from suspicious hosts 6098 1676 0 Enforce minimal number of blocks 5252 1443 0 Require service bit 1 3812 898 0 Require minimum uptime 3738 877 0 Require a known and recent user agent 3715 869 0 Filter out hosts with multiple bitcoin ports 512 512 0 Look up ASNs and limit results per ASN and per net ``` The new ASN max seeds of 10 allows for 512 IPv6 addresses to be included, up from the ~150 that was filtered by the previous version. While there is more to do for #17020 , these changes I think are fairly isolated from the rest and should make it a bit easier for others to get up to speed with what the functions in the script do.
